The only reason Barcelona is in such bad shape is the financial crisis. Xavi could have built a stronger squad if not for the financial crisis and would have been able to strengthen the Barcelona team as well. Xavi is failing to stabilize this team only because of financial crisis.
Everyone wants Barcelona to sell their current players to sign new players to the club, so their performance should be better than this next season. We all understand the situation going on with the club, Barcelona did not have enough money to sign top players to perform at a high level because since Messi left the club this is the not the same Barcelona we once knew, if Messi does not leave as a free agent I believe they would have enough money to sign more players when he left. Even though the club decided to sell the halve of their squad I don't think they will have enough money to buy the top players they need. I hope we remember that two players are willing to remain in the club next season, Cancelo and Felix. I won't be surprised if Barcelona rely on their current players next season.
However, Xavi thinks it was because of the bad financial situation in Barcelona and he said they can't buy players like the other team while I think he is right but Laporta doesn't have a good relationship with Xavi after he said that, and that's why it seems we can finally see Hansi Flick working in Barcelona since he is also interested for it.
Xavi is right, the club has enough players who went to another club on loan this season, and they were unable to sign players like other clubs. Xavi managed the club with the available players, and they will finish the season in the second position. I think the management expects the club to achieve more than this in La Liga with their current players, and I don't think that is going to happen even in the coming season because Real Madrid will always make it difficult for them. Although Xavi announced in the past few months that he's going to leave at the end of the season, maybe he already knows that his time with the club will end after this season. I don't think Barcelona would have another coach who can manage the players like Xavi Hernandez.
