UEFA has opened disciplinary proceedings against Barcelona, Juventus and Real Madrid over their involvement in the proposed European Super League.
The clubs were part of the 12 ‘founding’ members of the breakaway league, which later collapsed.
The other nine clubs renounced the project but Barcelona, Juventus and Real Madrid have refused to do so.
UEFA said proceedings had been opened against the three “for a potential violation of UEFA’s legal framework”.
In a statement released on Tuesday, UEFA said: “Following an investigation conducted by UEFA ethics and disciplinary inspectors in connection with the so-called ‘Super League’ project, disciplinary proceedings have been opened against Real Madrid, Barcelona and Juventus for a potential violation of UEFA’s legal framework.
“Further information will be made available in due course.”
The other nine clubs involved – Arsenal, Chelsea, Liverpool, Manchester City, Manchester United, Tottenham Hotspur, AC Milan, Inter Milan and Atletico Madrid – have been punished by European football’s governing body for their participation.
They have agreed to make a combined €15 million goodwill contribution to benefit children’s and grassroots football across Europe.
They will also have 5% of UEFA competition revenues withheld for one season, starting in 2023-24, and this money will be redistributed, including in the UK.
Each has also committed to UEFA and its competitions, with the clubs facing fines of €100 million apiece if they seek to join an unauthorised competition in the future. They will be fined half that if they breach any other terms of the declaration.
Real Madrid president Florentino Perez, who was appointed as chairman of the ESL, recently said that the 12 clubs that agreed to join the project have “binding contracts” and “cannot leave”.
