In fact, the current coach of Barcelona, Xavi, has to be praised. I think if Xavi had not joined the Barcelona team, this team would not have regained its performance. Now as a coach, I think the players should fulfill their responsibility to ensure Xavi's dream of La Liga title.
It must be appreciated indeed that Xavi is able to improve Barcelona's performance slowly and it hasn't fully returned to the way Barcelona used to be and even all of that requires a long process.
Barcelona is now almost certain to get the La Liga title, but if you look at Barcelona's overall performance, it is still very disappointing, especially on the European stage, there is not much that Barcelona can do when they are unable to qualify from the UCL group and lose in the Europa League.
The matter of being able to get the La Liga title this season is inseparable from the lack of meaningful competition from rivals so that Barcelona is very comfortable at the top of the standings without any pressure from other teams.
