Champions League

The UEFA Champions League, previously known as the European Cup and abbreviated as UCL or UEFA CL, is an annual club association football competition. It is organized by the Union of European Football Associations (UEFA) and contested by top-division European clubs. The challenger decides the winners through a round-robin group stage where teams must qualify for a double-legged knockout format and a single-leg final. It is the world's most-watched club competition and the third most-watched football competition, following the UEFA European Championship and the FIFA World Cup. It is one of the world's most prestigious football tournaments, played by the national league champions and runners-up of their national associations.
