Seeding

The qualified teams were 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.

Format

In the knockout stages, the 16 teams played a single-elimination tournament, with the following rules:

Each tie was played on a home-and-away two-legged basis, with the higher-seeded team hosting the second leg. However, CONMEBOL required that the second leg of the finals must be played in South America, i.e., a finalist from Mexico must host the first leg regardless of seeding.
In the round of 16, quarterfinals, and semifinals, if tied on aggregate, the away goals rule was used. If still tied, the penalty shoot-out was used to determine the winner.
In the finals, if tied on aggregate, the away goals rule was not used, and 30 minutes of extra time was played. If still tied after extra time, the penalty shoot-out was used to determine the winner.
If there were two semifinalists from the same association, they must play each other.
