They started blaming Xavi for the bad results they got and they were saying Xavi is guilty for the bad performance they had. However, Xavi and his team got improved after that, especially after beating Napoli in the Champions League. But I think Barcelona is trying to find another coach for the next season.
But They also tried to make Xavi stay in the team. In between Barcelona and Las Palmas, Xavi started talking about it in the conference before the match and he said, he was thankful to Deco and the other people on the team but he made his decision to leave Barcelona and he is not going to change it.
Making arrangements for the well being of the club should be concerning for Barcelona and their players. Barcelona president, Joan Laporta have done his best for the team but easier jobs are not triggered due to the high intensity of these challenges flowing in for elite team. Blaming Xavi Hernandez for the incompetent actions shouldn't be the worry of this club. Barcelona are well inform and they're capable of bringing back to back prominent results from games upward, why are they struggling for a win?
