UEFA on Friday announced sanctions, including financial punishments, against nine of the 12 clubs behind the aborted Super League project, after the clubs "apologised" and acknowledged "a mistake". The governing body of European football said that "in a spirit of reconciliation" the nine clubs had agreed to a "Club Commitment Declaration" and accepted a five percent cut in their European revenue for one season. However, three clubs, Barcelona, Real Madrid and Juventus, did not sign the declaration. UEFA said it "reserved all rights to take whatever action it deems appropriate against those clubs that have so far refused to renounce the so-called 'Super League'. 

"The matter will promptly be referred to the competent UEFA disciplinary bodies," the statement concluded. Some media have reported that UEFA is contemplating a two-year ban from European competition for the three holdouts, the maximum its rules allow. However, their options are clouded by a ruling from a commercial court in Madrid on April 20. The court banned UEFA and FIFA from making any moves to block a Super League or taking any disciplinary measures against the clubs, players or officials involved. It is also unclear what penalties the clubs that have withdrawn may owe to the remaining clubs for breaking their agreement to join the Super league. The nine clubs that opted out of the project -- Tottenham, Arsenal, Manchester City, Manchester United, Chelsea, Liverpool, Atletico Madrid, Inter Milan and, the last to withdraw, AC Milan -- have agreed to a series of "reintegration measures".
