The two Milan giants and Atletico Madrid followed all six English Premier League clubs in pulling out of the European Super League on Wednesday, dealing a fatal blow to the project.
The withdrawals by Manchester City, Manchester United, Liverpool, Arsenal, Chelsea and Tottenham came just 48 hours after the league’s unveiling late on Sunday following a furious response from fans and officials.
The three Italian clubs involved — Juventus, AC Milan and Inter Milan — admitted defeat and La Liga leaders Atletico Madrid also pulled out.
Real Madrid and Barcelona — the last of the initial group of 12 clubs to sign up — have yet to make any comment but the project in its current form is dead in the water.
AC Milan were one of the main drivers behind the plans, having missed out on the Champions League for the past seven seasons.
The seven-time European champions said the change was necessary due to the changing football landscape but admitted they “must be sensitive to the voice of those who love this wonderful sport”.
Italian champions Juventus said they remained “convinced of the soundness of the project’s sport, commercial and legal premises” but accepted it could not go ahead in its original form.
British Prime Minister Boris Johnson hailed the English pull-outs, telling parliament: “The announcement was the right result for football fans, for clubs and for communities across the country.”
The English Football Association also welcomed the withdrawals, praising fans for “their influential and unequivocal voice”.
Reigning European champions Bayern Munich and French giants Paris Saint-Germain had both come out strongly opposed to the breakaway league, dealing it a heavy blow.
Adding to the drama on Tuesday, Manchester United announced that executive vice-chairman Ed Woodward would step down from his role at the end of 2021.
Several players at the English clubs had voiced opposition to the Super League, and Manchester City manager Pep Guardiola commented: “It’s not a sport when success is already guaranteed.”
