Each tie in the knockout phase, apart from the final, was played over two legs, with each team playing one leg at home. The team that had the higher aggregate score over the two legs progressed to the next round. In the event that aggregate scores finished level, the team that scored more goals away from home over the two legs progressed. If away goals were also equal, 30 minutes of extra time were played. If there were goals scored during
extra time and the aggregate score was still level, the visiting team qualified by virtue of more away goals scored. If no goals were scored during extra time, the tie was settled via a
penalty shoot-out. The draw mechanism for each round is as follows: • In the draw for the round of 16, matches were played between the winners of one group and the runners-up of a different group, with the group winner hosting the second leg. Teams from the same group or same association cannot be drawn against each other. • From the quarter-finals onwards, these restrictions did not apply and teams from same group or same associations may be drawn against each other. In the final, the tie was played over just one leg at a neutral venue. If scores were level at the end of normal time in the final, extra time was played, followed by penalties if scores remained tied. ==Qualified teams==
