2021 Copa Sudamericana

On 2 October 2020, CONMEBOL's Council approved the implementation of format changes to the Copa Sudamericana starting from this edition, aimed at ensuring that each of the countries is better represented in the different stages of the competition. The following changes were implemented: • The tournament was expanded from 54 to 56 teams, with all four Copa Libertadores third stage losers entering the competition instead of the two best teams eliminated. • In the first stage, teams from all associations other than Argentina and Brazil played against a team from their same association in double-legged ties with the winners qualifying for a 32-team group stage, ensuring that at least two teams from each association will take part in the group stage. • A group stage was included, with teams from Argentina and Brazil directly entering the Copa Sudamericana entering the competition at this stage, joining the 16 first stage winners and the four teams eliminated in the Copa Libertadores third stage. The winners of each group qualified for the round of 16. • The eight third-placed teams of the Copa Libertadores group stage entered the competition at the round of 16. ==Teams==

The following 44 teams from the 10 CONMEBOL associations qualified for the tournament: • Argentina and Brazil: 6 berths each • All other associations: 4 berths each The entry stage is determined as follows: • Group stage: 12 teams (teams from Argentina and Brazil) • First stage: 32 teams (teams from all other associations) A further 12 teams eliminated from the 2021 Copa Libertadores were transferred to the Copa Sudamericana, entering the group stage (four teams) and the round of 16 (eight teams). ;Notes ==Schedule==
