I’d be feeling sorry for him, except we didn’t sign anyone.
Mou needs to start doing the other half of management and that is coaching players to make them better, rather than just focusing on the tactical point of view. Look at Poch, Guardiola and Klopp. They’re all on the training field making their players better - individually. Mou needs to do that rather than have people handed to him at their peaks. It’ll also mean that players can actually be moulded into what he wants them to be.
All through his career he’s had teams bought for him - time to show he’s as good as Fergie and start using that amazing academy United have.
