It's awful watching him play. He's a hinderance to every attack. He can't turn with the ball, he can't dribble, he loses every contest with a defender, his first touch has completely deserted him, his pace over 10 yards is gone, his awareness of players around him is nonexistent, he takes too long to get a shot away, his energy levels are totally depleted, he can't pass anymore.
Worst of all, he's keeping Martial out of the striker's position. He had to beat two men today every time he received the ball and he still looked infinitely more dangerous than Rooney.
