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 scored more goals on aggregate over the two legs advanced to the next round. If the aggregate score was level, then 30 minutes of
extra time were played (the
away goals rule was not applied). If the score was still level at the end of extra time, the winners were decided by a
penalty shoot-out. In the final, which was played as a single match, if the score was level at the end of normal time, extra time was played, followed by a penalty shoot-out if the score was still level. The mechanism of the draws for each round was as follows: • In the draw for the knockout round play-offs, the eight group runners-up were seeded, and the eight Europa League group third-placed teams were unseeded. The seeded teams were drawn against the unseeded teams, with the seeded teams hosting the second leg. Teams from the same association could not be drawn against each other. • In the draw for the round of 16, the eight group winners were seeded, and the eight winners of the knockout round play-offs were unseeded. Again, the seeded teams were drawn against the unseeded teams, with the seeded teams hosting the second leg. Teams from the same association could not be drawn against each other. • In the draws for the quarter-finals onwards, there were no seedings, and teams from the same association could be drawn against each other. As the draws for the quarter-finals and semi-finals were held together before the quarter-finals were played, the identity of the quarter-final winners was not known at the time of the semi-final draw. A draw was also held to determine which semi-final winner would be designated as the "home" team for the final (for administrative purposes as it was played at a neutral venue). ==Schedule==
