I think Xavi still wants to be at Barcelona and the players also still want Xavi to remain their coach, but there is another thing that made in this team. Not because he doesn't like it, but he has the best way to get something more appropriate. Actually, Barcelona's performance is not bad, but management always demands the best that they want to receive. Indeed, that is a normal thing, but they also have to be able to see and adapt to their current conditions.
I heard that Barcelona also seems to have the opportunity to keep Xavi for next season, but that is a rumor that I heard and the truth has not yet been confirmed. However, if that really happens, then Xavi must ask for something that can be included in the contract, so that he does not receive something that he experienced this season. I really understand if management puts pressure when Barcelona's performance is very bad, but that's not what happens, they always force what they want, even though logically it is difficult.
Xavi says that he is not appreciated, maybe he would like to stay with the players, but it is difficult to work in such an environment. I very much doubt that Xavi will remain in the team, if he announced it officially, he will do it. But I am also confident that he will not remain without a team for long, he showed himself very well in Barcelona, and if he gets into a team with good financial opportunities, he can achieve excellent results in any other team. He did a great job at Barcelona, considering the time he joined the team.
Xavi is a good coach, but just some periods that he was faced with challenges on inconsistency, and decline in his team performance, he was criticize as an unexperienced coch and not competent enough to coach Barcelona. This made him feel bad and decided to leave the club which he made the announcement officially.
If Barcelona wants him to stay, then they need to make him happy and feel at home at all time, not only when he is victorious, and they say a lot of crap when he is facing hard time with his team. Now that he has put Barcelona back to a good form, and they have being consistent with their matches, they want him to stay. Forgetting all those crap that they said. If I was to be in Xavi shoes, I would leave the club.
