Two of the biggest clubs in the world have filed appeals to the Court of Arbitration for Sport (CAS).
Europa League champions Chelsea and English domestic treble champions Manchester City are challenging decisions made against them by FIFA and UEFA, respectively.
Chelsea appealed on Friday against a transfer ban imposed by FIFA in February for breaching transfer and registration rules for players under 18, charges Chelsea denies.
The London club was fined $600,000 but more importantly was banned from signing players this summer or in the January 2020 transfer window.
Chelsea appealed the ban in April but FIFA’s Appeal Committee only partially upheld it by allowing the club to register youth players during the next two transfer periods.
On Thursday, Manchester City lodged an appeal to CAS after UEFA decided there was cause to pursue punishment of the club over allegations that it breached UEFA’s Financial Fair Play (FFP) regulations.
If Man City is found guilty, the UEFA Club Financial Control Body (CFCB) could throw the Premier League champions out of European competition, including the Champions League.
The club denies it has done anything wrong. UEFA launched an investigation in March following a report in Der Spiegel that said Man City’s owners in the United Arab Emirates had overvalued certain sponsorships in order to comply with FFP requirements.
CAS says “it is not possible to say at this time” when a decision will be reached in either case and added that no further information on either case would be provided before the decisions are announced.
