Format

The knockout phase involves 32 teams: 21 teams which received a bye, and the 11 teams which advance from the qualifying round (ten group winners and the best runners-up).^[4]

Each tie in the knockout phase, apart from the final, is played over two legs, with each team playing one leg at home. The team that scores more goals on aggregate over the two legs advances to the next round. If the aggregate score is level, the away goals rule is applied, i.e. the team that scores more goals away from home over the two legs advances. If away goals are also equal, then 30 minutes of extra time is played. The away goals rule is again applied after extra time, i.e. if there are goals scored during extra time and the aggregate score is still level, the visiting team advances by virtue of more away goals scored. If no goals are scored during extra time, the tie is decided by penalty shoot-out. In the final, which is played as a single match, if scores are level at the end of normal time, extra time is played, followed by penalty shoot-out if scores remain tied.^[2]

In the knockout phase, teams play against each other over two legs on a home-and-away basis, except for the one-match final. The mechanism of the draws for each round is as follows:

In the draw for the round of 32, the sixteen teams with the highest UEFA club coefficients are seeded (with the title holders being the automatic top seed),^[5] and the other sixteen teams are unseeded. The seeded teams are drawn against the unseeded teams, with the seeded teams hosting the second leg. Teams from the same association or the same qualifying round group cannot be drawn against each other.
In the draw for the round of 16, the eight teams with the highest UEFA club coefficients are seeded (with the title holders being the automatic top seed should they qualify),^[5] and the other eight teams are unseeded. The seeded teams are drawn against the unseeded teams, with the order of legs decided by draw. Teams from the same association cannot be drawn against each other.
In the draws for the quarter-finals and semi-finals, there are no seedings, and teams from the same association can be drawn against each other. As the draws for the quarter-finals and semi-finals are held together before the quarter-finals are played, the identity of the teams in the semi-finals are not known at the time of the draw. A draw is also held to determine the "home" team for the final (for administrative purposes as it is played at a neutral venue).

Qualified teams

Below are the 32 teams which participate in the knockout phase (with their 2017 UEFA club coefficients, which took into account their performance in European competitions from 2012–13 to 2016–17 plus 33% of their association coefficient from the same time span).^[5]^[4]
