# 2009 Copa Libertadores knockout stage

The last four stages of the 2009 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.

### Tie-breaking

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

### Seeding

The 16 qualified teams in the knockout round will be seeded according to their results in the group stage. The top teams from each group are 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 are seeded 9-16, with the team with the most points as seed 9 and the team with the least as seed 16. Teams with a higher seed will play the second leg of each tie at home.
