UEFA president Aleksander Ceferin has made clear the 12 European Super League clubs must face the consequences for their involvement in the planned breakaway competition.
Less than 48 hours after the official announcement of the tournament, and following a huge public backlash to the plan, the 'big six' from the Premier League – Arsenal, Chelsea, Liverpool, Manchester City, Manchester United and Tottenham – all ended their involvement.
Ceferin has praised the English clubs for a willingness to admit they made a mistake, but that will not mean they avoid punishment – albeit it is unclear yet what action the governing body will take.
In an interview with the Mail on Sunday, the UEFA chief revealed how he has placed the teams in different tiers while comparing Barcelona, Juventus and Real Madrid to those who believe Earth is flat, with that trio still remaining aligned to the initial proposal.
"Everyone has to take consequences for what they did and we cannot pretend nothing happened," Ceferin told the newspaper.
"You cannot do something like that and just say: 'I've been punished because everybody hates me'. They don't have problems because of anyone else but themselves. It's not okay what they did and we will see in next few days what we have to do.
"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'.
"For me there are three groups of this 12 — the English six, who went out first, then the other three [Atletico Madrid, Inter and Milan] after them and then the ones who feel that Earth is flat and they think the Super League still exists. And there is a big difference between those.
"But everyone will be held responsible. In what way, we will see. I don't want to say disciplinary process but it has to be clear that everyone has to be held responsible in a different way.
"Is it disciplinary? Is it the decision of the executive committee? We will see. It's too early to say."
There was widespread condemnation of the Super League from fans, governing bodies and former players alike, leading to financial backers JP Morgan to admit they "misjudged how the deal would be viewed by the wider football community".
UEFA announced changes to the Champions League format on Monday, including an increase from 32 to 36 clubs as the current group stage system is to be shelved in favour of a single league.
Clubs will get to play four extra matches per season, with the top eight in the final table advancing through to the last 16. Those placed between ninth and 24th will enter a play-off round to decide who else will qualify for the knockout stages, while those 25th and lower are eliminated and do not enter the Europa League.
The radical reforms to the competition are scheduled to come into place for the 2024-25 season.
