He's 18 years old with plenty of time to get better. I've been saying for a while, we could try to turn him into a LB. His defense was meh, while his attacking was impressive in the Championship so they turned him into a LW. But for a club with United's standards and with Martial already on the left wing, trying to convert him back to a LB could be worth it. I doubt any LB would be as good as he is going forward. I don't know if that happens though seeing as we have Shaw.
