The Court of Arbitration for Sport (CAS) has officially registered Manchester City’s appeal against their two-year ban from European club competition.
The Premier League champions were also fined 30m euros for “serious breaches” of Uefa’s financial regulations.
The club has vowed to fight the sanction imposed by UEFA on February 14 for breaching financial fair play regulations.
In a statement, CAS said: “The Court of Arbitration for Sport has registered an appeal filed by Manchester City football club against the Union of European Football Associations.”
If the appeal against the ban fails, Man City faces losing hundreds of millions of pounds in prize money, TV revenue, gate receipts and sponsorship income.
Last week City Football Group CEO Ferran Soriano said the club hoped to have their appeal heard by CAS before the start of next season’s Champions League.
He dismissed UEFA’s charges against the club of overstating their sponsorship revenue between 2012 and 2016 and failing to cooperate with an investigation as false.
