Matty James was with United until last season, when he moved to Leicester City.
Reece told MUTV: "Matty is a massive influence on my career. I remember watching him when I was 10 years old and I still watch him now he's at Leicester. He watches my games, either on MUTV or live, and tells me where I can improve as a player.
"He's helped me at left-back because you can have similar attributes to the midfield position. I was trying to do better than him but, at the same time, it was very pleasing to see what he was doing, like captaining England [youth side] at Wembley. It was a great day for all the family to watch him there."
