Real Madrid and Atlético Madrid feud over derby officiating controversy

Real Madrid's 2–1 defeat to Atlético Madrid on September 20, 2026, has led to ongoing disputes regarding officiating decisions. Madrid criticized challenges made by Cristian Romero and Kang-in Lee, while Atlético defended their performance and accused Madrid of overreacting. The Technical Committee of Referees remarked that Kang-in's challenge on Fede Valverde warranted a red card, although it wasn't given during the match. Tensions escalated off the pitch, resulting in the ejections of assistant coaches Pedro Machado and Pablo Vercellone following a confrontation in the tunnel at halftime. Real Madrid's media voiced concerns about alleged officiating double standards, questioning the fairness of the decisions made during the match.
