2015 Copa Libertadores final stages

The 2015 Copa Libertadores final stages played from April 28 to August 5, 2015. A total of 16 teams competed in the final stages to decide the champions of the 2015 Copa Libertadores.

The winners and runners-up of each of the eight groups in the second stage qualified for the final stages.

The qualified teams were seeded in the final stages according to their results in the second stage, with the group winners seeded 1–8, and the group runners-up seeded 9–16.

In the final 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 had to be played in South America, i.e., if there was a finalist from Mexico, they would have to host the first leg regardless of seeding.
• In the round of 16, quarterfinals, and semifinals, if tied on aggregate, the away goals rule would be used. If still tied, the penalty shoot-out would be used to determine the winner (no extra time would be played).
• In the finals, if tied on aggregate, the away goals rule would not be used, and 30 minutes of extra time would be played. If still tied after extra time, the penalty shoot-out would be used to determine the winner.
• If there were two semifinalists from the same association, they would have to play each other.

The bracket of the final stages was determined by the seeding as follows:

• Round of 16:
  • Match A: Seed 1 vs. Seed 16
  • Match B: Seed 2 vs. Seed 15
  • Match C: Seed 3 vs. Seed 14
  • Match D: Seed 4 vs. Seed 13
  • Match E: Seed 5 vs. Seed 12
  • Match F: Seed 6 vs. Seed 11
  • Match G: Seed 7 vs. Seed 10
  • Match H: Seed 8 vs. Seed 9
• Quarterfinals:
  • Match S1: Winner A vs. Winner H
  • Match S2: Winner B vs. Winner G
  • Match S3: Winner C vs. Winner F
  • Match S4: Winner D vs. Winner E
• Semifinals: (if there were two semifinalists from the same association, they would have to play each other)
  • Match F1: Winner S1 vs. Winner S4
  • Match F2: Winner S2 vs. Winner S3
• Finals: Winner F1 vs. Winner F2

The finals were played on a home-and-away two-legged basis. If tied on aggregate, the away goals rule would not be used, and 30 minutes of extra time would be played. If still tied after extra time, the penalty shoot-out would be used to determine the winner.

Since UANL are from Mexico, they had to host the first leg regardless of seeding (Regulations Article 3.7b: "El Torneo deberá indefectiblemente finalizar en un país perteneciente al continente sudamericano. Para tal caso, de llegar a las finales un equipo que no pertenece al continente sudamericano, deberá indefectiblemente jugar su primer partido de local." English translation: "The Tournament shall invariably end in a country belonging to the South American continent. Therefore, provided that a team not belonging to the South American continent qualifies to the finals, it shall invariably play the first leg at its home.")

The first leg was played on July 29, and the second leg was played on August 5, 2015.
