2023 Copa Sudamericana
The 2023 Copa CONMEBOL Sudamericana was the 22nd edition of the CONMEBOL Sudamericana, South America's secondary club football tournament organized by CONMEBOL.
The final was played in Maldonado, Uruguay on 28 October 2023. Originally scheduled to be held in Montevideo, on 15 April 2023 it was announced that the final would be played at Estadio Centenario, however the match was confirmed to have been moved to Estadio Domingo Burgueño in Maldonado on 15 September 2023.
Ecuadorian club LDU Quito were the champions, winning their second title in the competition after defeating Brazilian club Fortaleza 4–3 on penalties following a 1–1 draw after extra time in the final. As winners of the 2023 Copa Sudamericana, LDU Quito earned the right to play against the winners of the 2023 Copa Libertadores in the 2024 Recopa Sudamericana. They also automatically qualified for the 2024 Copa Libertadores group stage.
Independiente del Valle were the titleholders, but did not defend their title since they qualified for the 2023 Copa Libertadores group stage as Copa Sudamericana champions and later advanced to the knockout stage.
Format changes
On 19 December 2022, CONMEBOL announced format changes to the Copa Sudamericana starting from this edition while maintaining the same number of matches to be played. The following changes were implemented:- The first stage of the tournament, where teams from all associations play against a team from their same association, was played over a single match instead of a home-and-away two-legged basis.
- The eight group runner-ups were not eliminated, but instead played a play-off round prior to the round of 16 against the eight third-placed teams of the Copa Libertadores group stage, which previously advanced directly to the round of 16. The winners of this round advanced to the round of 16 along with the Copa Sudamericana group winners.
