Champions League quarter-finals come to an end this week, with the second legs set to get underway. If any of the matches were to go to extra-time, some teams may be relying on away goals to get them through to the next round.
Chelsea will be hosting Porto in the Champions League on Tuesday night, albeit in an unfamiliar stadium.
The tie will be played in Seville, Spain to comply with current Covid restrictions, with the Blues leading Porto 2-0 from the first leg.
Elsewhere, Paris Saint-Germain take a 3-2 lead back to the Parc des Princes when they face Bayern Munich.
Manchester City and Liverpool both play on Wednesday, against Borussia Dortmund and Real Madrid, respectively.
Do away goals count in extra time?
If both teams are level on aggregate after the two legs, and have also scored the same number of away goals, the match will go to extra-time.
Away goals do still count in extra-time, meaning the team that’s at home will have to score twice if the away team scores once.
The only way a tie will go to a penalty shootout, therefore, is if neither team scores in extra-time.
Even though a number of clubs have played at neutral venues for their Champions League ties, away goals still count.
Chelsea haven’t reached the Champions League semi-finals since the 2013-2014 campaign.
They lost 3-1 to Atletico Madrid over two legs at the time, and didn’t go on to win any other matches in the knockout phase of the competition until this year.
Meanwhile, Manchester City are the favourites to win this year’s Champions League.
Pep Guardiola’s side haven’t reached the semi-finals since 2016, where they lost 1-0 to Real Madrid over two legs.
