Your memory of the season seems very selective. Leicester and Brighton in particular we didn’t create much at all.So as we know, he's having a poor season so far.
Against Newcastle he looked very slow, dithered on the ball and got tackled/intercepted many times.
He's in charge of building our play from the back, and he's doing a poor job, he just doesn't move or pass the ball fast enough.
As soon as he was moved into defence in the 2nd half, our play rose dramatically. While you can argue that was mainly because Newcastle sat back and tried to hold on, we also pressured them back and won the ball higher up the pitch than usual.
When I think back to the start of the season, we played Fred,Pereira and Pogba. While this midfield wasn't perfect we certainly got the ball forward better and created more chances.
Jose then decided to drop Pereira for Fellaini, and we continued playing well.
Matic was then brought back into the team, and since then we've struggled.
Jose seems to play him every match whether he's good or bad, and his current form is detrimental to the team.
Our best periods of play and chance creation came against Tottenham (first half), Burnley, Watford and Young Boys.
I thought Matic played well and Improved our flow and balance once he entered the team this season, but he’s been deteriorating by the game. Maybe he can’t take the intensity, or maybe he is afflicted by what the reat of the team is afflicted by.
