Lashing out at the three clubs — Real Madrid, Barcelona and Juventus — who are yet to formally withdraw from the European Super League, UEFA president Aleksander Ceferin compared those who believe that the breakaway competition “still exists” to flat-earthers.

The 53-year-old has refused to rule out a ban from next season’s Champions League for all 12 clubs involved in trying to set up the ESL.

However, he opined that the six English clubs — Chelsea, Manchester City, Arsenal, Tottenham, Liverpool and Manchester United — showed some greatness in backing out first and deserve greater leniency, according to reports from Britain’s Mail. 

The Slovenian lawyer, elected UEFA president in 2016, added: “But for me it’s a clear difference between the English clubs and the other six. They pulled out first, they admitted they made a mistake. You have to have some greatness to say: ‘I was wrong.'”

Ceferin said their stance was in contrast to that of Real Madrid, Barcelona and Juventus, ridiculed by Ceferin as “the ones who feel that Earth is flat and… think the Super League still exists.”

In the space of 48 hours beginning last Sunday, UEFA, aided by fans and politicians, quelled a mutiny by English, Spanish and Italian clubs attempting to form a quasi-closed tournament designed to supplant the existing Champions League.

However, nine clubs, including all six in England, subsequently withdrew.

Meanwhile, Ceferin said disciplinary action remained an option for UEFA, European football’s governing body.

“Everyone has to take consequences for what they did and we cannot pretend nothing happened,” he warned.

“But everyone will be held responsible. In what way, we will see,” he added.

However, the irony is that UEFA were on the brink of enacting changes that would have similarly entrenched the position of many of the established Champions League powers behind the Super League.

But Ceferin said he was open to dropping the two extra Champions League spots in an expanded competition that were meant to be reserved for clubs based on their historic record.

Meanwhile, Ceferin also thanked British Prime Minister Boris Johnson for his opposition to the Super League.
