He's improved very little in terms of his all round game. He'll get some things right, several things wrong, his failure to control Rashfords cross in the first half is a decent example...And he wasn't very positive in everything he did, it's a weird claim, several time he gets dispossessed of the ball because he lacks awareness, same happened in the Liverpool match, gets the ball inside the box when its rolling towards the corner flag, he has no awareness of the situation so when he turns you have Lovren just stealing the ball straight from him. Same thing happening again and again, plenty of times he'll look up to cross, lose overview, defender just takes the ball and runs...Then there's the odd situation where he delivers a magnificent cross we score from.
I don't disagree that he was man of the match against Chelsea, plenty of times I've agreed that Fellaini has had the man of the match performance..
And using pundits as an argument is bizarre.
