Real Madrid step up Negreira battle with Barcelona by requesting compliance records; ask UEFA to strip titles won during that periodThe long-running Negreira case has taken another significant turn, with Real Madrid making a legal request in their battle against Barcelona.While the sporting consequences of the case remain uncertain, the legal process is moving forward, and Real Madrid appear determined to play an active role rather than waiting for the outcome.Notably, the relationship between Spains two biggest clubs has deteriorated sharply since the investigation began.According to AS, Real Madrids legal team has asked the judge overseeing the case to order Barcelona to hand over documentation relating to the clubs compliance system between 2010 and 2018.In fact, the Los Blancos have also urged UEFA to strip Blaugrana of the titles they won during the Negreira scandal.Whether that request ultimately has any legal or sporting effect remains to be seen, as no final decision has been reached and the judicial process is still ongoing.What Real Madrid are asking the court to examineAccording to the report, Real Madrid want access to Barcelonas compliance framework from the relevant years in order to determine what anti-corruption mechanisms were in place and whether those measures were properly implemented.The clubs lawyers have also requested that Spains Civil Guard provide invoices, payment authorisations, internal procedures and audit documents linked to Tresep, Radamanto and Best Norton.Those companies have featured during previous stages of the investigation, and Real Madrid argue that some of the requested material has not yet been incorporated into the case file.From a legal perspective, it is understood that the club wants to complete a factual record before the judicial process advances.UEFAs role remains one of the biggest questionsAlthough the Spanish courts continue to examine the case, any potential sporting sanctions fall under a different jurisdiction.As the report notes, UEFA is the governing body with the authority to impose sporting penalties in European competitions if it considers disciplinary action appropriate under its regulations.This explains why developments in court and developments within footballs governing institutions are happening separately.Regardless of how the investigation eventually concludes, the Negreira case has had a lasting impact on the relationship between Barcelona and Real Madrid, something that is now beyond repair.
