The knocked-out stages will play two legs, a game at home for each of the 16 teams, and will play away to their respective opponents. The best eight are paired by a raffle draw for a place in the Semifinals.
● UEFA has removed the away goals rule from the Champions League this season.
● If a tie is a level at the end of the second leg, extra time and penalties will take place as required, regardless of the number of away goals each team has scored.
● Managers are permitted to name up to 12 substitutes in their match squad and a maximum of five can be used during the 90 minutes at no more than three stoppages of play.
A sixth substitution and additional stoppage of play are available if a match goes to extra time.
● Players who have joined a new club before the knockout stages are eligible to feature regardless of any previous participation in European competition this season.
