He brings the ball out well and then misplaces a pass and at top PL level you get punished.
I hope I am proved wrong and Harry goes on bigger and better things, but I can't see playing for a top 6 team regularly.
He's been playing regular top flight football for 12 months and has already progressed the extent he has. At his age he still has a lot of improvement in him. At this rate he'll be playing CL football within 24 months.
