#4 There are serious weaknesses in his squad
In the early years of his career, Mourinho was a master at improving players. He did it at Porto, in his first spell at Chelsea, and at Inter Milan. However, we haven’t seen too much of that since though, and it is difficult to point to a single player he has made better over the past six or seven years. This is now proving a real weakness for him at Old Trafford.
This current squad is so far short of the quality of Manchester City’s, Chelsea’s and Liverpool’s. Apart from in goal, almost every position has weaknesses. Defensively, they are increasingly vulnerable. No one has yet been able to hold down a spot in midfield, and going forward, there are times when they have looked toothless. Mourinho’s big name players- the likes of Paul Pogba, Alexis Sanchez and Romelu Lukaku- continue to let their manager down, and that is shown in their recent results.
