#2 Youth development derailed
Under Alex Ferguson, Manchester United were renowned for their development of world stars from the academy, and players signed at a young age. Mourinho has a history of derailing academy and youth programs at all his previous clubs, instead relying on more experienced aged members of his squad consistently.
Marcus Rashford, Anthony Martial, Matteo Darmian and Luke Shaw have all been sidelined for older heads and their development has been stunted. These are players who have the potential to be world beaters and need to be encouraged and given minutes.
