UEFA president Aleksander Ceferin has threatened to ban the four clubs who haven’t yet left the Super League from the Champions League.
There were 12 clubs in the Super League when it was announced on Sunday, only for the plan to spectacularly collapse over a 48-hour period as eight clubs pulled out.
However, Real Madrid, Barcelona, Juventus and AC Milan have not yet officially left the competition.
“It’s crystal clear that the clubs will have to decide if they are Super League or they are a European club,” Ceferin told The Associated Press.
“If they say we are a Super League, then they don’t play Champions League, of course … and if they are ready to do that, they can play in their own competition.
“For me, it’s a very different situation between the clubs that admitted their mistake and said, ‘We will leave the project.’
“The others mainly know I would say that this project is dead, but they don’t want to believe it, probably.”
