Another problem is Injuries.
We know that when they were knocked out of the Champions League their form in the Champions League and La Liga faltered because they lost 4 core players in midfield and defense.
Xavi is good at coaching, but he still can't balance rotations so when their core players don't play Xavi gets overwhelmed and can't perform all out as usual.
Xavi's problem is going to look much bigger for now in this January 2023 when he finds out that he cannot integrate another player into his team because he knows that the team does not have that much money, and that he has to work with the ones he has, although for me that is not a bad thing, only now it is what I can speculate, in any case, I have to wait, I don't know if Barceloa's plans are to sell some players so that they have sufficient capitalization, the economic problems are something that He stopped this team from everything, and one of Barcelona's mistakes was that Xavi chose everything, and each one of the managers trusted him and it hasn't given results, for me it's a pity, because Barcelona is one of the best teams they have in the League.
I think Xavi understood - Azpilicueta discloses how he rejected BarcelonaI actually don't know much about their finances now, they are often talked about always having financial problems but their spending this season is really crazy and it's not fair to say they have financial problems because of their determination.
At the moment they will prioritize free players, Azpilicueta was one that was always linked with Barcelona in the previous season but in the end he extended the contract but still did not rule out Barcelona chasing him moreover they still need a defender especially Pique has also left now.
