I am certainly not giving Mourinho an "easy ride". The players you refer to have been assembled over several years by a recruitment process that has failed us dismally. Where I hold Poch culpable is that he was part of that process for over five years. Mourinho has had less than a full season so far.
I don't agree with much of Mourinho's team selections, tactics and general management of our club, but he largely can't be held responsible for the players he had no input in buying. What was evident to me on Sunday was that Man U players ( as with other teams this season such as West Ham and Leicester) look so much taller, stronger and more physical than our team. It was like pygmies against giants . Also, even though they had a game away in Europe on Thursday, they looked fitter and stronger than many of our players who were palpably tiring in the second half.
Why isn't Hichens doing his job? He needs to go and a decent DoF needs to be recruited asap.
