What happened: Barcelona issued an official statement urging La Liga, the RFEF and the CTA refereeing committee to take action against Real Madrid president Florentino Perez. The statement is a direct retort to Real Madrid, who had confirmed submitting a dossier to UEFA against Barcelona over the Negreira case. The two clubs are now trading formal complaints through the game's governing bodies.

Why it matters: This is a sharp escalation in the institutional conflict between Spain's two biggest clubs, moving the Negreira dispute from public statements into formal demands for sanction. Barcelona's move follows its formal letter to LaLiga, RFEF and the referees' committee, raising the stakes for how Spanish football's authorities respond.

What to watch: Watch for responses from La Liga, the RFEF and UEFA, and whether either club files further complaints.
