The Premier League's 'big six' and Milan, Inter and Atletico Madrid have affirmed their commitment to UEFA competitions after acknowledging "the Super League project was a mistake" and apologizing "to fans, national associations, national leagues, fellow European clubs and UEFA".
All nine clubs must abide by a set of "reintegration measures" in order to be allowed back into the UEFA fold.
These include commitments to UEFA Statutes and to competing in existing UEFA competitions for which they qualify, rejoining the European Club Association and taking "all steps within their power" to terminate their involvement in the company established to run the Super League.
The clubs will also contribute to a €15million goodwill fund to be used for youth and grassroots football in Europe, while they will see five percent of UEFA club competition revenues withheld for one season. UEFA says that revenue money will also be redistributed.
Should any of the nine clubs attempt a similar breakaway in future, they will be fined €100m. Breaching any other aspect of the Club Commitment Declaration – the agreement signed to enable their return to UEFA competitions – will incur a fine of €50m.
Manchester United, Manchester City, Chelsea, Arsenal, Tottenham, Liverpool, Milan, Inter and Atletico all renounced the Super League following significant opposition from fans, players and sponsors over their proposed involvement.
UEFA president Aleksander Ceferin said: "I said at the UEFA Congress two weeks ago that it takes a strong organization to admit making a mistake especially in these days of trial by social media. These clubs have done just that.
"In accepting their commitments and willingness to repair the disruption they caused, UEFA wants to put this chapter behind it and move forward in a positive spirit.
"The measures announced are significant, but none of the financial penalties will be retained by UEFA. They will all be reinvested into youth and grassroots football in local communities across Europe, including the UK.
"These clubs recognized their mistakes quickly and have taken action to demonstrate their contrition and future commitment to European football. The same cannot be said for the clubs that remain involved in the so-called 'Super League' and UEFA will deal with those clubs subsequently."
