He is, but to be fair to McTominay he did actually get good results doing it last season. Fellaini was always more myth than ability. We would bring him on, yes he was large and win some balls in the air but he wasnt that good with his head missing plenty of chances and not getting or setting up many goals. McTominay did deliver the goals
However we need to strengthen midfield and selling McTominay wouldnt weaken us much in that area, especially if we signed someone... anyone. Ugarte still seems likely coming in which would be a big improvement. It does weaken us for goals off the bench but we should be looking for a better solution than a decent goal poacher who is picked in midfield. A striker who is a goal poacher or a good midfielder who scores a goal now and then would be better options.
As for today he had a nice turn, a good touch... And then he was on the post for the set piece and got drawn to the ball on the 2nd cross instead of defending the back post so the ball went over his head and brighton scored.
