Yes, Barcelona's success this season in La Liga is 90% Real Madrid's credit. In fact, due to internal problems, Real Madrid could not perform at their usual level and Barcelona became the champion in the absence of competition. But in fact, Xavi has had terrible results in two seasons: elimination from the Champions League in the early stages plus elimination from the Europa League. This is a weak result considering how much money is spent on transfers.
Barcelona's success this season in La Liga is not due to Real Madrid's credit, Lol. Because basically, Xavi has restored Barcelona since Xavi replaced Ronald Koeman and at that time, even though Barcelona failed to win the title, but Xavi was able to restore Barcelona's performance quickly.
This season, Xavi can still continue his ability to make Barcelona consistent for good results in La Liga. With this result, Xavi really managed to restore Barcelona's best form even though it was only in La Liga and it wasn't because Real Madrid was weak. lol! Because, if you think Real Madrid is weak, then of course Real Madrid will also fail in the Champions League but in fact that is not the case.
