If there was no Xavi, maybe Barcelona would have fallen even deeper. We can see that when Xavi first arrived, he handled the Barcelona team which was already in a very bad state with all the problems they were facing, but slowly Xavi built this team with adequate finances provided by the team management.
It sounds very strange if Xavi is blamed for the decline in Barcelona's performance this season, the team management must actually be responsible because they did not provide full support for Xavi to build this team.
At the end of the season Xavi has decided to leave the team and I think that will make Barcelona very difficult and I think with their new coach next season they will not have a large percentage to be better than this season, I am very pessimistic about that.
Agree with you. Maybe if it weren't for Xavi, Barcelona would be even worse. Luckily, Xavi came to their rescue and succeeded in bringing Barcelona to the LaLiga trophy last season despite the financial crisis. The problems currently facing Barcelona are so complete that blaming Xavi as the culprit for Barcelona's decline is an unwise action.
Because I see Xavi is a genius future coach and those who say Xavi has to go, they don't know his game. They only criticize things they don't even know about, when Xavi needs the best defensive midfielder he knows what he is talking about and this is just the start, barcelona just needs to bring in the players he wants and be patient in the process because what he is doing right now is not perfect . But now he has decided to leave Barcelona and this decision will not change even if Barcelona wins the UCL title. Xavi's decision to leave Barcelona is final and will not change.
