Phil Neville, Nicky Butt and Paul Scholes all have coaching roles with United.
Asked if it makes him jealous to see his great friends coaching the Reds, he told MUTV: "It does a little bit! When my eldest son came up here to train for a week, I saw Butty training the U21s, Phil with the first team and Scholesy with Butty.
"It's great to see they are still part of the club and training the young kids. There is nothing better than to have players like that, who you've seen being successful over the years, training the young kids. That's what Manchester United do."
