All clubs willing to join the European Super League will be thrown out of the Union of European Football Associations.

Since most clubs withdrew, whether ESL will be started in the near future is unclear. There isn't any cause for the UEFA to take action as of now.

Since most clubs withdrew, whether ESL will be started in the near future is unclear. There isn't any cause for the UEFA to take action as of now.On April 18, 2021, twelve of Europe's top football clubs from England, Spain, and Italy announced that they would form The European Super League (ESL). It proposed a new mid-week competition that would break away from the Premier League. The competition structure would have pitted the founding clubs and their guests against each other for prize money.

The ESL's founding clubs included AC Milan, Arsenal FC, Atletico de Madrid, Chelsea FC, FC Barcelona, FC Internazionale Milano, Juventus FC, Liverpool FC, Manchester City, Manchester United, Real Madrid CF, and Tottenham Hotspur. Three more clubs were scheduled to join before the start of the inaugural season. The Union of European Football Associations (UEFA) warned clubs associated with a breakaway ESL that forming a rival to the Champions League will jeopardize domestic and international competitions.

April 18, 2021, UEFA stated that they condemn the formation of ESL in a press release. "The clubs concerned will be banned from playing in any other competition at domestic, European or world level, and their players could be denied the opportunity to represent their national teams," as per the press release.

All six Premier League clubs, Manchester City, Chelsea, Arsenal, Liverpool, Manchester United, and Tottenham Hotspur, withdrew from the ESL as of April 20, 2021. Following the removal of Juventus, AC Milan, Atletico Madrid, and FC Internazionale Milano from the ESL on April 21, 2021, only FC Barcelona and Real Madrid remain.

Manchester City announced to the BBC that they have "formally adopted the procedures to withdraw" from the Super League. Liverpool's participation in the planned breakaway league has been "discontinued," according to the club. Manchester United said that in making their decision not to participate, they "listened carefully to the reaction from our fans, the UK government, and other main stakeholders." Arsenal apologized to their supporters in an open letter, saying they had "made a mistake" and that they would withdraw after listening to them and the "broader football culture."

If UEFA or the UK government follow through with their threats to ban the twelve football clubs from joining the Super League, they will be fined. Neither UEFA nor the UK government has taken any action against those who want to enter the Super League. They have not yet been expelled from the UEFA association. In an interview with Sky Sports UEFA President, Aleksander Ceferin said, "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."
