FC Barcelona has filed a complaint with UEFA concerning the refereeing during their UEFA Champions League quarter-final against Atletico Madrid, which concluded with a 3-2 aggregate loss. Despite their 2-1 victory in the second leg held on April 14, 2026, at the Estadio Riyadh Air Metropolitano in Madrid, the Catalan club expressed dissatisfaction over key officiating decisions. They highlighted a denied penalty for a foul on Dani Olmo and a late red card for Eric Garcia as pivotal moments that influenced the match. Barcelona's official statement criticized the refereeing performance, asserting that it did not adhere to the Laws of the Game and that the VAR system failed to intervene appropriately in significant incidents. The club believes these errors resulted in substantial sporting and financial repercussions. This complaint follows an earlier submission regarding officiating in the first leg, which UEFA dismissed as inadmissible. Barcelona hopes for a more favorable response this time and aims to work with UEFA to improve refereeing standards.
