I honestly sympathize for him because Carrick seems to have been trying for ages (i.e. under Ole as well) to turn him into a holding DM, which is just not his game whatsoever and shines a light on his worst qualities - defensive positioning and reading of the game.
If used correctly - a more attacking #8 role - Scott can be a very effective player, but we arent seeing that right now. I think he has done alright the last couple of games - much better than the Caf would claim - but he just looks like he isnt entirely comfortable in the role he is being asked to play. On the occasions he got further up the pitch or was able to carry the ball forward from midfield, he looked good. It will be interesting to see what Rangnick chooses to do with him.
