Because according to my predictions, Xavi seems to have felt uncomfortable at Barcelona for quite a long time. Because it can be seen from Barcelona's performance this season that it is not good. Even in the last match against Villareal, Barcelona had to go home with a defeat. So with this fact, it seems like Xavi is tired of managing Barcelona.
Maybe this chaos is caused by Barcelona's lack of finances. So it was from this that the seeds of all the chaos in Barcelona started.
No coach should want his team to lose even if he doesn't feel comfortable in the team. I don't think it's because they're tired, but they're not in good shape. The unfavorable condition of the club will worsen mentally. I think they are still on a good track, they only lost 3 times until today. Tomorrow they play Osasuna, they should be able to win because they're at home. Barcelona's La Liga chances aren't gone yet, they still have a chance, there are still a lot of games.
