Agreed with the majority of it, except probably Mata. He can be a very effective rotation player. When playing through the middle and linking with pogba/rashford/herrera he can do a serious amount of damage.
Lukaku is a strange one.. I would love to see the lukaku we had end of last season before he got injured again.. he was immense. But under jose he was woeful,and i mean really bad, and doesnt seem to be as reviatlised as some of the others, his touch and control is just awful at times. Although he somehow still puts the ball away in the net, i cant see him lasting too long if he doesnt change.
For me Matic has barely put a foot wrong since Ole has come in.. Which is mad because under Jose he was dreadful. Only thing has really changed is that hes sticking to playing that line in front of the back 4 and not venturing too far past that. If thats what hes good at, keep him doing that.
Jones has looked alright under Ole, but I agree is is a liability/ complete hand grenade. not good enough to be starting.
Ole's style so far is doing exactly what a good coach should be doing.. enhancing the skills of good players. There will eventually deadwood that needs getting rid of, and it will become more apparent and clear before the end of the season.
