Since Xavi is staying, that means that he will want to end the season as well as he could hope for. Finishing third isn't in the plans, deciding to stay and then finishing third and dropping one place after the announcement of staying doesn't seem that great for him. I am sure that it will not be easy at all, but Barcelona needs to get all the wins and hope that Girona drops points somewhere because they really need to get back to second place. Second place at La Liga isn't that horrible, it could happen, its understandable, you can't win always and last year they won, so it is not really a big deal. But third place would be quite terrible, like if it was Athletico Madrid then I would maybe understand, but not to Girona.
