According to The New York Times, at least 12 teams have either signed up as founding members or expressed an interest in joining a European breakaway league.

Real Madrid, Barcelona and Atlético Madrid are the three teams from Spain who have reportedly agreed to join the new league.

UEFA and the top European leagues are bracing for an announcement on Sunday. Officials have spent the weekend in talks about ways to block the plan, including potentially banning the breakaway teams from domestic leagues and from next season’s Champions League. The breakaway is scheduled to begin in 2022.
