Crystal Palace have launched an official appeal with the Court of Arbitration for Sport (CAS) after being demoted from the Europa League to the Conference League due to a breach of UEFA's multi-club ownership regulations.

Mr López was in possession of Menotropin in violation of the UCI Anti-Doping Rules and took delivery of the substance sometime between May 1-5, 2022.

"The panel examined the evidence, including the Club Leon trust set up by the owners of the club, and concluded that this trust was insufficient to comply with the regulations."

FIFA's decision to exclude León from the Club World Cup due to shared ownership with Pachuca undermines competitive integrity, an issue being appealed at CAS.
