European Super League

The Unify League (UL), previously known as the European Super League (ESL), was a proposed seasonal football competition for clubs in Europe. It was supposed to be organised by the European Super League Company SL, a commercial enterprise created to rival or replace the UEFA Champions League. The initial iteration of the league entailed 20 teams, with 15 of them being founding members of the competition. Almost all teams had withdrawn immediately in April 2021 owing to public backlash; by 2025, following Barcelona's withdrawal, only Real Madrid had remained in the proposed competition format, withdrawing in February 2026.
