So what? If he show improvment in all aspects, I don't care that Xavi wouldn't be a coach in the summer.
I just don't think the players will respect Pocch enough, with his history. Now if the board say "Mauricio, we want you to lead the new project which will continue if one of our candidates win the elections. We are going to clear out Pique,Busquets, Suarez and replace them with harder working options at your discretion within our budget. You have full trust and backing with the squad selection" then he is the better choice. All he needs to do is apologize for past comments and start his job.
But with the small window until the end of the season, I don't think we are going to have the major personel changes we need. And in that scenario I trust more in Koeman to stand his ground and bench who is not working hard enough, and for the amigos to respect that- atleast initially.
Just my 0.02c, and I could be reading Pocchetino's mentality all wrong.
