European football governing body UEFA has warned clubs linked to a breakaway Super League that they face being banned from domestic and international competitions if they set up a rival to the Champions League.

In a joint statement with Spanish, English and Italian leagues and federations, UEFA said it will consider “all measures”, including the courts and bans from domestic leagues, in opposition to plans for a breakaway competition.

Twelve clubs have agreed to form a European Super League which will rival the prestigious UEFA Champions League.

The clubs are Manchester United, Liverpool, Manchester City, Arsenal, Chelsea, Tottenham, Barcelona, Real Madrid, Atletico Madrid, Inter Milan, AC Milan and Juventus.
