In recent days, when comparing to A Madrid and R Sociedad ,Barcelona is really performing well and that needs to be on 5th place. Yes I am not aware of how best Barcelona was, but yes the current coach is really giving out his best to the players I suppose. I am sure , if the players follow him then, he is going bring back Barcelona's earlier performances back.
This is an opportunity for Xavi when Atletico Madrid and Real Sociedad have had bad things in their game, so behind Barcelona being able to catch up to the top 5 in LaLiga it is very possible for Xavi to reach it slowly but surely.
I understand what you are saying that there must be a long room for Xavi so that he can be free to find talent from these young talent, it is very easy to judge who will be chosen by Xavi who stands out in his game.
