# 2010 Copa Libertadores knockout stage

The last four stages of the 2010 Copa Santander Libertadores are the knockout stages: the Round of 16, the Quarterfinals, the Semifinals, and the Finals.

## Format

The remaining stages of the tournament constitute a single-elimination tournament. In each stage, the teams will play an opponent in a two-legged tie on a home-away basis. Each team will earn three points for a win, one point for a draw, and zero points for a loss. The team with the most points at the end of each tie will advance. Fourteen teams will advance from the second stage; the eight group winners, the six group runners-up teams with the best records. The remaining two entries will go to Mexican clubs Guadalajara and San Luis.

### Tie-breaking

The following criteria will be used for breaking ties on points:
* Goal difference
* Away goals
* Penalty shootout

### Seeding

The 16 qualified teams were seeded according to their results in the Second Stage. The top teams from each group were seeded 1–8, with the team with the most points as seed 1 and the team with the least as seed 8. The second-best teams from each group were seeded 9–16, with the team with the most points as seed 9 and the team with the least as seed 16. Guadalajara and San Luis were given the 13 and 14 seed, respectively, which they had earned in the 2009 Copa Libertadores.
