Champions League away goals rule: what happens if there is a draw?

The 2021/22 Champions League knockout stage gets underway later this evening with an important change to the rules - one which determined so many ties in previous editions of the tournament. In June last year, UEFA took the decision to abolish the away goals rule in all two-legged European ties. Introduced in 1965, the away goals rule stated that all goals scored by the visiting team in both home and away legs would count as double if the aggregate score ended level. 

Many famous victories were celebrated due to the away goals rule over the years - Andrés Iniesta broke Chelsea's hearts by bagging a stoppage-time winner at Stamford Bridge in the 2008/9 semi-final - the tie ended 1-1 but it was Barça, as the visitors, who advanced. The Catalans found out what it feels like to be on the receiving end of the away goals rule when Roma heroically clawed their way back after losing the first leg 4-1 to win 3-0 on home soil. The tie ended 4-4 on aggregate but Edin Dzeko's goal at Camp Nou counted as double, so the Italians progressed to the semis.

Parking the bus

However, in recent years, teams playing at home would simply focus on avoiding conceding any goals at all - even if it meant putting 10 men behind the ball and defending for 90 minutes. It didn't make for entertaining football - the kind we have come to expect in the world's greatest club competition. Teams parking the bus in the first leg also put the visiting team at a disadvantage later, when the tie was to be decided at their ground.

UEFA explained why the away goals rule had to go and what will replace it: “With the decision to remove this rule, ties in which the two teams score the same number of goals over the two legs would be not decided on the number of goals scored away, but two 15-minute periods of extra time are played at the end of the second leg and in case the teams score the same number of goals or no goals during this extra time, kicks from the penalty mark would determine the team which qualifies to the next stage of the competition”.

Extra-time, then a penalty shootout if need be

So from today, all two-legged ties which end level after the home and away matches have been played will go to extra-time - 15 minutes per half. At the end of that, if the score is still level, the game will be resolved from the penalty spot - a shootout involving five players from each side which will go to sudden death if it remains level after both teams have taken all of their five spot-kicks.

UEFA gave examples of recent statistics to illustrate their decision to make the historic change: "Statistics since the mid-1970s show a clear trend of continuous reduction in the gap between the number of home-away wins (from 61%-19% to 47%-30%) and the average number of goals per match scored at home-away (from 2.02-0.95 to 1.58-1.15) in men’s competitions".
