Format
The group winners and runners-up of the second stage qualified for the knockout stages. The sixteen teams played a single-elimination tournament. In each stage, teams played in two-legged ties on a home-away basis, with the higher-seeded team playing the second leg at home. Each team earned 3 points for a win, 1 point for a draw, and 0 points for a loss. The following criteria were used for breaking ties on points, except for the final:[5]
For the final, the first tiebreaker was goal difference. If tied on goal difference, the away goals rule would not be applied, and 30 minutes of extra time would be played. If still tied after extra time, the title would be decided by penalty shootout.
If two teams from the same association reached the semifinals, they would be forced to play each other.
The 16 qualified teams are seeded in the knockout stages according to their results in the second stage, with the group winners seeded 1–8, and the group runners-up seeded 9–16.[5] The teams were ranked by: 1. Points (Pts); 2. Goal difference (GD); 3. Goals scored (GF); 4. Away goals (AG); 5. Drawing of lots.
The Finals were played over two legs, with the higher-seeded team playing the second leg at home. If the teams were tied on points and goal difference at the end of regulation in the second leg, the away goals rule would not be applied and 30 minutes of extra time would be played. If still tied after extra time, the title would be decided by penalty shootout.[5]
