He has lost so much confidence in an attacking sense, shame to see. At Saints, he was a tremendous crosser of the ball and really good at picking out runs into the box.. now he is like a left footed Valencia. I think he is either over thinking it or he is just feeling anxiety about keeping his place in the side.. or it may just be he needs a consistent run of games with a wide man in front of him. Either way he needs to up his game in an attacking sense because he can't be playing for Manchester United's first XI and be a shit crosser.
Time is on his side however.
