What is the away goals rule?
In knockout rounds of European club competitions, if the score of a two-legged match is level on aggregate after 180 minutes of play, then the team who has scored more away goals progresses to the next round.
What happened this year when matches were held at neutral venues?
During the global pandemic, several games, including Chelsea’s, Manchester City’s and Liverpool’s Champions League round of 16 ties, Arsenal’s Europa League matches against Benfica and Manchester United’s ‘away’ match against Real Sociedad all took place at neutral venues because of travel restrictions.
The away goals rule, however, still stood despite games being played at neutral grounds.
Who suffered because of the rule this year?
Juventus and Bayern Munich were knocked out of this year’s Champions League tournament because of the rule.
The holders Bayern Munich drew 3-3 on aggregate with Paris Saint-Germain in the quarter-finals but lost on away goals.
Juventus, meanwhile, were held to a 4-4 aggregate draw against Porto and exited the competition having scored fewer away goals.
