A22 Sports Management, the company behind the European Super League project, has formally filed a lawsuit against UEFA seeking €4–5 billion in damages, alleging that UEFA continues to maintain monopolistic control over European club football. The move follows a 2023 ruling by the Court of Justice of the European Union (CJEU), which found UEFA’s exclusive authority over competitions to be anti-competitive. A22 claims UEFA’s new 2024 regulations contradict that ruling and have caused financial harm to Super League clubs. Despite months of discussions between A22 and UEFA from March to September 2025, no resolution was reached. A22 had proposed a new competition called the ‘Unified League’ with a modern format and its own digital platform, ‘Unify’. If successful, the lawsuit could trigger one of the biggest structural and financial shifts in European football history, potentially redefining club competitions, revenue distribution, and governance.
