5 reasons why Manchester United are no longer the dominant force they once were

#3 Too much experimentation with the squad

Mourinho is yet to find the best playing XI of Manchester United so far.

Mourinho has been experimenting a bit too much with different lineups and different starting XI this season. He has tried out his preferred 4-3-3 formation, a 5-3-2 formation and a bizarre 3-5-1-1 formation so far.

Just take a look at the players he lined-up against Tottenham, we see that he had made 6 changes to the squad. And again coming into this weekend he made 3 changes against Newcastle and constant change has been the trend so far this season for the Red Devils.

This is a clear deviation from the past under Ferguson, who virtually played with the same starting XI unless forced by an injury. This show of confidence in players inspired them to give their best on the pitch.

Mourinho is not doing any favours to the players by making changes so frequently. It makes players more concerned about their spot in the starting lineup than their performance on the pitch.
