The winner of each match up is determined by aggregate score. In the Round of 8, quarterfinals and semifinals, if the two teams are tied on aggregate the higher seeded team advances. In the final, if the two teams are tied after both legs, the match goes to extra time and, if necessary, a penalty shoot-out.
