There is a concern with Mourinho, because of what happened with Chelsea last year, and to some extent his last moments at Madrid. In both these situations he was unable to deal with pressure and he cracked under it.
It's a very delicate situation for us, because Jose needs time, but also in the same regard we should keep it in the back of our minds that there is a very plausible chance that he has 'lost it'. Failing this time around will be more severe than ever. We've got everything we wanted, a PL proven manager with arguably the best CV around, 3 world class players in Zlatan, Mkhi and Pogba (who we broke the WR for), and he's been given total control over the squad to implement his way of playing. If it doesn't work, where do we go next?
The people laughing off our results so far are equally as daft as those suggesting Mourinho is not the right guy from this. From my POV we should no more than simply accept this one of the possibilities. What is more relevant however is that our results are extremely alarming right now, and needs urgent intervention from Jose. What this is, is the million dollar question, but that's what he is employed to find out. As fans we should not be blindly supporting the manager, but doing our best to critically evaluate the situation at every opportunity.
