If you are talking about the old Mourinho from a decade ago, then maybe someone like him would be the right one for that position. But Mourinho has long passed his peak. He isn't as good and as dedicated as he used to be and you can see how he is doing with Roma. The only thing I liked about him is that he refused an offer from Saudi Arabia and did not just leave Roma behind and grab the money.
The very experienced coaches won't go to Manchester United I think as the season is done for them. They are not good enough to compete for anything of importance I think. It is only 5 points to Tottenham, but being behind Tottenham and Newcastle doesn't make me think that they could outplay those two teams at any time this season.
I agree with this because we know in several years in Mourinho's prime he was one of the coaches who could not be denied in terms of performance and leadership for a club even the nickname The Special One was indeed worth pinning to this coach but indeed his prime began to fade at this time due to several conditions such as his behavior which was indeed odd and the emergence of several new coaches who could indeed compete better than Mourinho.
He can indeed be said to still be one of the good enough coaches but indeed his current performance in coaching a club is so pronounced that we cannot force him to become one of the great coaches because all the old ones will be replaced by those who are new.
At the moment it seems that he to the SPL club is still not possible because if he want, from last season when there was already a large enough offer but it was rejected by Mourinho because indeed his ambition is still very big but it does not rule out the possibility for next season if in the end his performance does not increase at his current club.
