Anfield, 7 May 2019. Liverpool had lost the first leg of their Champions League semi-final 3-0 in Barcelona. They won the second leg 4-0, and for one night the most important number on the scoreboard was not the score of the match in front of the crowd. It was the total across two matches, six days apart, in two countries: Liverpool 4, Barcelona 3.
That total is the aggregate score. In a two-legged tie each club plays once at home and once away, the goals from both matches are added together, and the club with more goals across the two goes through. Neither match has to be won. If the aggregate is level at the end of the second leg, the tie goes to thirty minutes of extra time and then penalties in UEFA's competitions and the EFL play-offs, and the Carabao Cup semi-final goes straight to penalties. Goals scored away from home have not counted extra since UEFA dropped the away goals rule in 2021.
What the aggregate score in football actually measures
A two-legged tie is one contest spread over two matches. The first leg does not produce a winner, whatever the result. It produces a lead, a deficit or a level position for the second leg to settle. That is the whole conceptual difference between a two-legged tie and a single match, and it explains every peculiarity of how they are played.
The arithmetic is simple. Club A beats Club B 2-1 at home in the first leg. The second leg, at Club B's ground, ends 1-1. Club A have scored three goals across the tie and Club B two. Club A win 3-2 on aggregate, despite drawing the second match.
The result of either match on its own does not decide anything. A club can lose a leg and still go through, and plenty have. A club can win a leg and go out. Supporters understand this instinctively, but it is the source of most of the confusion in the coverage of European football, because television graphics show the score of tonight's match first and the aggregate in smaller type underneath.
What the aggregate does not include
The aggregate counts goals scored in normal time and, where it is played, extra time in the second leg. It does not include penalty shoot-out kicks. A shoot-out is a separate tie-breaking procedure, not part of the match, and its kicks are recorded separately from the score. A tie that finishes 3-3 on aggregate and is won 4-2 on penalties is recorded as a 3-3 aggregate, with the shoot-out shown after it.

Reading it on screen: what "2-1 (agg 3-3)" means
A broadcaster's scoreboard during a second leg usually shows two scores. The first, in larger type, is tonight's match. The second, in brackets and often marked "agg", is the running total across both legs.
Take a tie in which the first leg ended 2-0 to the home side. In the second leg, the other club is winning 2-1 at home. The graphic reads "2-1 (agg 3-3)". The 2-1 is tonight's score; the 3-3 is the total. With the aggregate level, the tie is heading for extra time.
Newspapers and websites write the result in a slightly different form. The score of the match comes first and the aggregate in brackets, as in "Liverpool 4 Barcelona 0 (Liverpool win 4-3 on aggregate)", sometimes shortened to "4-3 agg". When the tie goes to extra time and penalties, "aet" (after extra time) and the shoot-out score are added, so "3-3 agg, aet, 4-2 pens" describes a tie decided on penalties after a level aggregate.
| What the scoreboard shows | What it means |
|---|---|
| 1-0 (agg 1-2) | Home side winning tonight, still behind on the tie by one goal |
| 2-1 (agg 3-3) | Home side winning tonight, tie level, extra time if it stays that way |
| 0-0 (agg 2-1) | Goalless tonight, the first-leg winners lead the tie |
| 3-1 aet (agg 4-3) | Extra time played, home side through on aggregate |
| 1-1 (agg 2-2, pens 5-4) | Tie level after extra time, settled by a shoot-out |
Which side is listed first
In a second leg, the home club is listed first in the match score and in the aggregate. That means the order of names in the aggregate flips between the first and second legs. The 2019 semi-final between Tottenham and Ajax read "Tottenham 0 Ajax 1" after the first leg in London and "Ajax 2 Tottenham 3 (agg 3-3)" after the second in Amsterdam. The convention is common rather than universal, and some broadcasters keep one club's name first in the aggregate throughout.
When the aggregate is level: extra time, penalties and no away goals
The procedure for a level tie is set by the competition's regulations, and the Laws of the Game leave it to them. In UEFA's competitions and the EFL play-off semi-finals, the order is the same. If the aggregate is level at the end of the second leg's 90 minutes and stoppage time, two fifteen-minute periods of extra time are played. If the aggregate is still level after that, the tie is decided by kicks from the penalty mark.
- First legNinety minutes plus stoppage time, whatever the score; no extra time is ever played.
- Second leg, normal timeNinety minutes plus stoppage time; if one club leads on aggregate, it goes through.
- Extra timeIf the aggregate is level, two periods of fifteen minutes, with an additional substitution allowed.
- PenaltiesIf the aggregate is still level, kicks from the penalty mark under the Laws of the Game decide the tie.
Applies from 2021-22 in all three UEFA club competitions. The EFL play-off semi-finals follow the same sequence; the Carabao Cup semi-final skips extra time.
There is no advantage for scoring away from home. Until 2021 there was. The away goals rule said that if the aggregate was level, the club that had scored more goals away from home went through, and only if away goals were also level did the tie go to extra time and penalties. Away goals counted in extra time too, which created the odd situation in which a goal scored by the visitors in extra time of the second leg was worth more than one scored by the home side.
UEFA announced the abolition in June 2021, effective from the 2021-22 season in all its club competitions. Its stated reason was that home advantage had been shrinking steadily since the mid-1970s, so the rule was rewarding something that no longer existed, and that it encouraged home sides in the first leg to defend against conceding rather than attack.
The Carabao Cup difference
The Carabao Cup semi-final follows a different sequence. The EFL removed extra time from the competition from 2018-19, except in the final, so a semi-final level on aggregate at the end of the second leg's 90 minutes goes straight to penalties. Chelsea and Tottenham played out the change in 2019: Tottenham won the first leg 1-0 at Wembley, Chelsea won the second 2-1 at Stamford Bridge, and with the aggregate at 2-2 the tie went directly to a shoot-out, which Chelsea won. Under the old away goals rule, Tottenham would have gone through. The wider rules for extra time and shoot-outs in English cup football are set out in our guide to extra time and penalties in English cup ties.
Where an English fan meets two legs, and where a single match is used instead
For English clubs, two-legged ties now appear in only three places. They used to be much more common.
The UEFA club competitions use them in the knockout rounds. In the Champions League, the Europa League and the Conference League, every knockout tie from the knockout phase play-off to the semi-final is played over two legs. The league phase is played as single matches, and the final is a single match at a neutral venue chosen in advance.
The Carabao Cup uses them in one round only. Every tie before the semi-final is a single match, and the final at Wembley is a single match. The semi-final is played home and away, normally in January, a survival from the competition's original two-legged design, and our guide to the Carabao Cup format explains the rest of its structure.
The EFL play-offs use two legs in the semi-finals of the Championship, League One and League Two. The club that finished higher in the league plays the second leg at home, and the semi-finals are followed by a single final at Wembley. The details of the Championship version are in our guide to how the Championship play-offs work.
Where English football uses one match
Most of English cup football is played over one match. The FA Cup is single ties throughout, with no replays from the first round proper since 2024-25, and its semi-finals and final are single matches at Wembley. The National League play-offs are single matches. The EFL Trophy is single matches. The FA Cup has never used two-legged ties in its rounds proper, except for a single season immediately after the Second World War, when the 1945-46 competition was played over two legs to raise money for clubs recovering from the war.
| Competition | Two legs used for | Single match used for | Level aggregate decided by |
|---|---|---|---|
| Champions League, Europa League, Conference League | Knockout play-off to semi-final | League phase and final | Extra time, then penalties |
| Carabao Cup | Semi-final | Every other round, including the final | Penalties, no extra time |
| EFL play-offs (Championship, League One, League Two) | Semi-finals | Final at Wembley | Extra time, then penalties |
| FA Cup | Not used | Every round | Extra time and penalties in the rounds proper |
| National League play-offs | Not used | Every round | Extra time, then penalties |
Who plays the second leg at home, and whether it is the advantage people assume
How the order of legs is decided varies between competitions. In UEFA's knockout rounds, it depends on the stage.
In the knockout phase play-off and the round of 16, the club that finished higher in the league phase plays the second leg at home. That is the reward for a better league-phase finish, and it is set out in the regulations. Beyond the round of 16, the order of legs in the quarter-finals and semi-finals is determined by the bracket and the draw, and UEFA has adjusted how much weight league-phase position carries there as the format has settled. The current season's regulations are the place to check.
In the Carabao Cup semi-final the order is decided by the draw. In the EFL play-off semi-finals, the higher-placed club in the league table plays the second leg at home.
Is the second leg at home an advantage?
The conventional wisdom says it is. The club at home in the second leg knows exactly what it needs, plays the decisive half of the tie in front of its own supporters and, if the tie goes to extra time, plays the extra thirty minutes at home too.
The evidence is weaker than the conventional wisdom. Academic analyses of European ties have reached mixed conclusions: some find a small edge for the club at home in the second leg, others find that it shrinks or vanishes once the strength of the two clubs is accounted for. The difficulty is that seeded clubs play the second leg at home, and seeded clubs are usually better. The better side wins more often whatever the order of legs, which makes the order hard to isolate.
Managers have their own preferences, and they are not unanimous. Some prefer the first leg at home, to establish a lead that the other side must chase. Others prefer the second, to know the target. The decline in home advantage across European football, which UEFA cited when it dropped away goals, has made the question matter less than it did in the 1970s, when travelling across Europe was harder and away crowds smaller.
How the first leg is played differently: leads, narrow defeats and the end of away goals
The first leg is played under different incentives from a single match. Losing 1-0 away is not a defeat in the way a single-match 1-0 defeat is. It is a one-goal deficit to make up at home with ninety minutes to do it.
That explains why many away sides in first legs play conservatively. A narrow defeat leaves the tie open. A heavy one ends it. Away managers in first legs historically valued a goal above almost anything, because under the away goals rule a 2-1 defeat was a much better result than a 1-0 defeat: if the return finished 1-0 to the side that had lost the first leg, the aggregate would be 2-2 and the away goal would put them through.
The abolition of away goals changed that calculation. A 2-1 away defeat and a 1-0 away defeat are now the same: one goal behind. The away team has no special reason to score unless it improves the margin, and the home team has no special reason to fear conceding unless it narrows the margin.
What changed in practice
Coaches argued about the effect before it happened, and the evidence since 2021 is still building. Two things are clear. First legs no longer have the specific pattern of home sides defending to avoid conceding an away goal, which was the most common criticism of the old rule. Second legs are simpler to follow. A club behind on aggregate needs to score as many goals as it is behind, and the arithmetic does not change depending on where the goals are scored.
One side effect is that more ties go to extra time. Under the away goals rule, a tie level on aggregate was often decided without extra time, because the away goals were unequal. Without the rule, every level aggregate goes to extra time.
Extra time falls only in the second leg: the complaint, and the answers to it
The objection is simple. Extra time can only happen at the end of the second leg, so it is always played at the ground of the club that is at home in the second leg. That club gets thirty more minutes of home advantage. If home advantage is real, the order of legs matters more than it should.
There are three answers given to it, and none of them is conclusive.
The first is that the advantage goes to the club that earned it. In UEFA's knockout play-off and round of 16, the club at home in the second leg is the one that finished higher in the league phase. In the EFL play-off semi-finals, it is the club that finished higher in the league. The extra time at home is part of the reward for a better season.
The second is that home advantage is smaller than it used to be. UEFA's own argument for abolishing away goals was that home advantage had been falling steadily since the mid-1970s. If home advantage is small over 90 minutes, it is small over 30.
The third answer is the one the away goals rule used to provide. Under the old system, an away goal scored in extra time counted extra, which gave the visitors something to aim for and was often defended as compensation for playing extra time away. When UEFA dropped away goals, it dropped that compensation too.
Alternatives that were tried
Football has tried several ways of deciding a level tie over the years. Replays were used in the early decades of European football, sometimes at neutral venues. Coin tosses were used before penalty shoot-outs were introduced. The golden goal, under which the first goal in extra time ended the match, was used in some competitions in the 1990s and early 2000s, and the silver goal, under which a side leading at the end of the first period of extra time won, was tried briefly. Our guide to the golden goal rule covers why both were dropped. The current procedure of extra time followed by penalties is the one that has lasted longest.
Cards, suspensions and substitutions across the two matches
The two legs of a tie are separate matches for disciplinary purposes. Cards shown in the first leg count towards the player's competition record, and a suspension triggered in the first leg can rule a player out of the second.
A red card in the first leg brings an automatic ban of at least one match, which in a two-legged tie is the second leg. A yellow card that takes a player to the competition's suspension threshold has the same effect. In UEFA's competitions the thresholds and the point at which yellow cards are wiped from players' records are set out in the disciplinary regulations; our guide to Champions League yellow card rules covers how the count works and when it resets.
Cards from domestic competitions do not count in UEFA's competitions, and UEFA cards do not count in domestic ones. In English competitions, the two legs of a Carabao Cup semi-final or a play-off semi-final are covered by the FA's and the EFL's disciplinary rules rather than UEFA's, and a ban earned in one domestic competition can be served in another.
Substitutions and registration
Substitutions in each leg are independent. A club has its full allowance of substitutes in each match, and a player taken off in the first leg can start the second. If extra time is played in the second leg, an additional substitution is allowed, along with an additional opportunity to make it.
Registration is a separate matter. A player has to be registered for the competition to play in either leg. In UEFA's competitions clubs can add a limited number of players to their squad lists before the knockout rounds, but a player signed after that cannot play in the knockout ties at all, which is why January signings sometimes appear in the Premier League but not in Europe.
The great aggregate comebacks by English clubs, and what each needed on the night
Most two-legged ties are won by the club that wins the first leg. The ones that are remembered are the exceptions.
Liverpool's 4-0 win over Barcelona in May 2019 needed three goals just to level the tie, and a fourth to win it without extra time. Divock Origi scored twice and Georginio Wijnaldum twice, the fourth from a quickly taken corner while the Barcelona defence was still organising itself. The aggregate was 4-3, and away goals played no part because the tie did not finish level.
Chelsea's comeback against Napoli in the 2012 round of 16 needed extra time. They had lost the first leg 3-1 in Naples, won the second 3-1 in normal time at Stamford Bridge to level the aggregate at 4-4, and won the tie when Branislav Ivanović scored in extra time. Chelsea went on to win the competition.
When away goals decided it
Two of the most celebrated English comebacks of 2019 depended on the away goals rule, which no longer exists. Manchester United lost 2-0 at home to Paris Saint-Germain in the first leg of their round of 16 tie, won 3-1 in Paris, and went through on away goals with a 3-3 aggregate after a stoppage-time penalty from Marcus Rashford. Tottenham lost the first leg of their semi-final 1-0 at home to Ajax, trailed 2-0 at half-time in Amsterdam, and won 3-2 with a Lucas Moura hat-trick completed in stoppage time. The aggregate was 3-3, and Tottenham went through on away goals. Under today's rules, both ties would have gone to extra time.
Middlesbrough's UEFA Cup run of 2006 had two comebacks in one season. They lost the quarter-final first leg 2-0 to Basel, went a further goal behind in the second leg at the Riverside, and won 4-1 to go through 4-3. In the semi-final against Steaua Bucharest they lost the first leg 1-0, trailed 2-0 in the second leg, and won 4-2 with a late goal from Massimo Maccarone. Fulham's 4-1 win over Juventus in 2010, after a 3-1 defeat in Turin and an early Juventus goal at Craven Cottage, is in the same category. The complete history of English clubs in European finals is in our guide to English clubs in European Cup finals.

|---|---|---|---|---|
| Liverpool v Barcelona, 2019 semi-final | Lost 3-0 | Won 4-0 | 4-3 | Aggregate |
| Chelsea v Napoli, 2012 round of 16 | Lost 3-1 | Won 4-1 aet | 5-4 | Extra time |
| Manchester United v PSG, 2019 round of 16 | Lost 2-0 | Won 3-1 | 3-3 | Away goals |
| Tottenham v Ajax, 2019 semi-final | Lost 1-0 | Won 3-2 | 3-3 | Away goals |
| Fulham v Juventus, 2010 round of 16 | Lost 3-1 | Won 4-1 | 5-4 | Aggregate |
Why ties are played over two legs at all
Two-legged ties exist for three reasons. Gate receipts come first: two legs mean two home matches, one for each club, and two sets of ticket sales. When the European Cup began in 1955-56, it was organised as a straight knockout played home and away so that every club played a home match in every round, and its finances depended on it. Television income, which now dwarfs gate receipts at the top level, came later.
Fairness is the second. A single match favours the home side, sometimes heavily. Two legs give each club a home match, and the aggregate removes most of the advantage of being drawn at home. In the days when travelling to the far side of Europe meant a long journey by rail or a propeller aircraft, that mattered more than it does now.
The home-and-away principle is the third, and the most deeply rooted. League football in England has always been home and away, and the early European competitions took the same approach. A two-legged tie is a short version of a league: each club gets to play the other at both grounds, and the better side over the two matches goes through.
Why the principle survives
Those reasons remain largely intact. Gate receipts are still significant for clubs outside the elite. Fairness still matters, because a single match at one club's ground is not a fair contest in the way a neutral venue or two legs are. The two-legged tie is also simply popular: a first leg sets up a second, and the week between them is a story in itself, which broadcasters value.
The objection is time. Two legs need two dates, and the calendar is crowded. That is why the FA Cup and the early rounds of the Carabao Cup use single matches, and why the EFL scrapped extra time. But at the stages where the stakes and the money are highest, two legs have survived.
Finals over two legs: the UEFA Cup until 1997, and why every final is now one match
For most of its history, the UEFA Cup final was played over two legs, home and away, like the rest of the competition. The final was not a single match at a neutral venue until 1998, when Inter beat Lazio in Paris. The last two-legged final, in 1997, was won by Schalke against Inter on penalties after both legs had finished 1-0 to the home side.
English clubs played in several of those two-legged finals, and the aggregate format produced results that a single final would not.
| Season | Final | First leg | Second leg | Aggregate |
|---|---|---|---|---|
| 1971-72 | Wolves v Tottenham | Wolves 1-2 Tottenham | Tottenham 1-1 Wolves | Tottenham 3-2 |
| 1972-73 | Liverpool v Borussia Mönchengladbach | Liverpool 3-0 | Mönchengladbach 2-0 | Liverpool 3-2 |
| 1975-76 | Liverpool v Club Brugge | Liverpool 3-2 | Brugge 1-1 | Liverpool 4-3 |
| 1980-81 | Ipswich Town v AZ | Ipswich 3-0 | AZ 4-2 | Ipswich 5-4 |
| 1983-84 | Anderlecht v Tottenham | Anderlecht 1-1 | Tottenham 1-1 | 2-2, Tottenham won on penalties |
The 1972 final was between two English clubs, Tottenham and Wolverhampton Wanderers, and was played at Molineux and White Hart Lane. Ipswich's 1981 final shows the format at its tightest: a 3-0 home win almost thrown away in a 4-2 defeat in the Netherlands. Liverpool came from two goals down in the first leg of the 1976 final against Club Brugge at Anfield.
Why all finals are now one match
The two-legged final had faults. It took two dates in an already full calendar. It meant the trophy might be presented at a ground half empty of supporters of the winning club. And it did not have the occasion of a single final, which broadcasters and sponsors increasingly wanted.
The League Cup made the switch earlier. Its finals were two-legged from 1961 to 1966, and moved to Wembley as a single match in 1967. The UEFA Super Cup moved to a single match in 1998. The European Cup final was always a single match at a venue chosen in advance, with a replay needed only once, in 1974, and since the UEFA Cup changed in 1998 every major European final has followed the same model.
The exceptions: single-leg ties at neutral venues, and grounds that cannot be used
Two-legged ties are the rule in UEFA's knockout rounds, but there are circumstances in which they cannot be played.
The most dramatic recent exception was the pandemic. In August 2020, after the season had been suspended for months, the Champions League and the Europa League finished with single-leg ties from the quarter-finals, played at neutral venues. The Champions League's finished in Lisbon and the Europa League's in Germany. Ties already part-played were completed over two legs at the original venues, which is why Manchester City played the second leg of their round of 16 tie against Real Madrid at home in August.
The 2020-21 season produced a second set of exceptions. Travel restrictions between countries meant that some ties could not be played at the home club's ground, and UEFA moved them to neutral venues. Liverpool played both legs of their round of 16 tie against RB Leipzig in Budapest, as did Manchester City against Borussia Mönchengladbach. Arsenal played Benfica in the Europa League in Rome and Athens. The aggregate format stayed the same; only the venues changed, and home and away became a matter of which dressing room each club used.
When a ground cannot host a leg
Other exceptions are less dramatic. A ground may be unavailable for safety reasons, because of a UEFA stadium closure imposed as a disciplinary sanction, or because it does not meet UEFA's stadium requirements for the round. Clubs in those situations play at another ground, sometimes in another city. Clubs from countries affected by war have played their home legs in other countries for whole seasons.
In English competitions, the EFL's and the FA's rules let the organisers move a match when a ground becomes unavailable, and the leg is then played elsewhere rather than dropped. The underlying principle stays the same: two matches, one aggregate, and the side with more goals over both goes through.
