So far I have also seen Xavi very good. Maybe if Xavi arrives early, the La Liga competition will be even more exciting. Actually I doubted when the beginning of him came. Looking at the experience he has only coached a few years, even then Xavi only coached in Asia. I think if Xavi gets the allotment of buying players, Barcelona will be a serious threat next season. Let's see, I'm sure they will make it difficult for Madrid next season.
It is doubtful that Barcelona will be financially capable of fighting for really top players, the club's management and Xavi constantly repeat this, so the situation does not change.
As for Xavi as a coach, I'm sure that as long as he coaches Barcelona, Real's position is protected. Theoretically, Real Madrid could have a crisis season when they lose to themselves, but I do not believe that Xavi is able to win the championship in the presence of strong competitors.
