Correct. It is unfortunate that many people blame Xavi for Barcelona's decline this season or more precisely their failure to defend the La Liga title. because currently it is almost impossible for them to catch up on points from Real Madrid. However, Xavi still has the opportunity to win the UCL League trophy. Xavi will concentrate fully on this competition and of course will give his best for Barcelona this season before leaving Barcelona.
However, what is certain is that Barcelona's decline this season is not necessarily Xavi's fault. However, individual mistakes, player injuries and players who are not performing well like Lewa are also factors that have damaged this season. Barcelona should give Xavi another season with good players and fewer injuries, then see how he dominates. However, Xavi has made the decision to leave Barcelona, maybe that is the best choice for Xavi.
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.
