UEFA are reportedly considering a two-year Champions League ban for clubs still committed to the European Super League project.
Twelve leading European clubs - dubbed the 'Dirty Dozen' - confirmed their desires to sign up for the breakaway league last month, only for the plans to crumble within a matter of days.
Despite widespread condemnation from fans, players, managers and authorities, four clubs in Barcelona, Real Madrid, Juventus and AC Milan are supposedly still trying to press ahead with Super League plans.
According to ESPN, UEFA are contemplating a two-year ban from Europe's elite competition for the quartet, although the four clubs believe that they can ultimately avoid such a punishment.
The report adds that the 'Big Six' Premier League sides and Atletico Madrid have contacted UEFA for talks over lesser sanctions, as the seven clubs are all intending to disassociate themselves from the Super League project.
However, Real Madrid president Florentino Perez - chairman of the Super League - has claimed that clubs have a binding contract to the competition which means that they "cannot leave".
