The Copa Sudamericana is an annual continental club football tournament, held in South America, organized by the South American Football Confederation (CONMEBOL). It is currently the second most prominent competition in South American club football. The origin of CONMEBOL Sudamericana dates back to 2002; it replaced the Copa Merconorte and Copa Mercosur. Since its inception, the competition is based on pure elimination, the number of rounds and teams that may vary. Copa Sudamericana is well-thought-out a merger of three tournaments: the Copa CONMEBOL, Copa Mercosur and Copa Merconorte. The winner of this tournament qualifies to play in the Recopa Sudamericana as well as in the Copa Libertadores, South America’s most premier club football championships.
