Enquanto Copa Libertadores e Liga dos Campeões da UEFA são ambas competições internacionais de futebol, existem algumas diferenças distintas entre a Copa Libertadores e a Liga dos Campeões da UEFA: Copa Libertadores is exclusively made up of teams from South American nations while the Champions League includes clubs from all over Europe. In Copa Libertadores, the top teams from each nation are invited to compete, while in Champions League, the top clubs must qualify through their respective domestic leagues. Copa Libertadores has a single-elimination format while Champions League uses a group stage system before transitioning into knockout rounds.
