A report that Europe's top teams are in talks to become founding members of a new competition shows "billionaire owners are out of control" and proves football cannot regulate itself, the Football Supporters' Association says.
A Sky News report said more than 12 teams from the top five leagues - in England, France, Germany, Italy and Spain - are in negotiations over what has been dubbed the 'European Premier League,' with a provisional start date in 2022.
"The latest reports of plots ... to create a European Super League, expose the myth that billionaire owners care about the English football pyramid, or indeed anything other than their own greed," the FSA said.
"This has to be the last nail in the coffin of the idea that football can be relied upon to regulate itself. These billionaire owners are out of control.
"Decisive action is now needed to protect the game we love," the group added.
European football governing body Uefa, whose blue-riband club competition is the Champions League, have reiterated their president Aleksander Ceferin's opposition to any such 'Super League.'
Uefa are already involved in talks about potential adjustments to the Champions League format and qualification path from 2024 and strongly resists breakaway threats.
"The principles of solidarity, of promotion, relegation and open leagues are non-negotiable,'' Uefa said.
"Uefa and the clubs are committed to build on such strength not to destroy it to create a super league of 10, 12, even 24 clubs, which would inevitably become boring.''
Spanish league president Javier Tebas said that "a project of this type will mean serious economic damage to the organizers themselves and to those entities that finance it.''
