Rules

Unlike most other competitions around the world, the Copa Libertadores historically did not use extra time, with the only exception the final match encounter, an additional period of play specified under the rules of a sport to bring a game to a decision and avoid declaring the match a tie or draw, or away goals, a method of breaking ties in football and other sports when teams play each other twice, once at each team's home ground, to decide a tie that was level on aggregate. From 1960 to 1987, two-legged ties were decided on points (teams would be awarded 2 points for a win, 1 point for a draw and 0 points for a loss), without taking goal difference into consideration. If both teams were level on points after two legs, a third match would be played at a neutral venue. Goal difference would only come into play if the third match was drawn. If the third match did not produce an immediate winner, a penalty shootout was used to determine a winner.

From 1988 onwards, two-legged ties were decided on points, followed by goal difference, with an immediate penalty shootout if the tie was level on aggregate after full-time in the second leg. Starting with the 2005 season, CONMEBOL began to use the away goals rule^] In 2008, the finals became an exception to the away goals rule and employed extra time. From 1995 onwards, the "Three points for a win" standard, a system adopted by FIFA in 1995 that places additional value on wins, was adopted in CONMEBOL, with teams now earning 3 points for a win, 1 point for a draw and 0 points for a loss.
