"You could play him in one of the wide positions as well because he likes to take players on. It'll be down to Sir Alex and his staff to work out what's best for him and the team.
"It's obviously going to be a big leap for him [from Crewe to United]," added Ritchie. "But we know he won't walk straight into the first team. He'll almost do a second apprenticeship here - he'll probably start off in the Reserves and be on the fringes for Carling Cup games and he might even go out on loan at some stage.
"I've certainly been impressed with what I've seen of him and he looks to be a very good talent."
