Surely Mourinho has to share the blame for what happened this season, but some people make him as some sort of antichrist, who came and plunged the world into chaos. Don't take serious his words of "this squad can't be improved". He also said: "Even if we say we’re very happy with our squad, we lie, because we always want to make it better". As for Schurrle, Salah, Luis, Luiz etc. Sure, they would have been useful players, but it wasn't Mourinho politics, that he can't buy someone, until club sell someone.
