Mass brawl broke out between police and dozens of radical fans in the bowels of El Sadar stadium after the Osasuna-Real Madrid match concluded. The incident was sparked when police attempted to identify the individual who threw a bottle onto the pitch during the match.
The controversy on the field, particularly regarding the VAR decision on Courtois' penalty against Ante Budimir, was overshadowed by the violent confrontation off the pitch, with authorities now investigating the incident and identifying potential suspects.
