He needs to be dropped in my opinion if Lingard starts mid week and plays well he should be starting the league games.
Mhiki’s form is becoming a growing concern, he’s in the team to create chances for our strikers and score goals and right now he isn’t doing either.
He looks tired and a bit short of speed, not as sharp as we saw him at times last season.
Feel for him to be at his best he needs the game to be end to end and fast paced when it’s a bit slow he seems to struggle and since Pogba has been injured his form seems to have gone.
