2011 Copa Sudamericana final stages


The final stages of the 2011 Copa Bridgestone Sudamericana de Clubes consisted of four stages:
The defending champion, Independiente, and the fifteen winners of the second stage qualified for the final stages. The sixteen teams played a single-elimination tournament, and were seeded depending on which second stage tie they won. 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:
  1. Goal difference
  2. Away goals
  3. Penalty shootout
For the final, the first tiebreaker was goal difference. If had tied on goal difference, the away goals rule would not have been applied, and 30 minutes of extra time would have been played. If still had tied after extra time, the title would have been decided by penalty shootout.
If two teams from the same association reach the semifinals, they would be forced to play each other.
