Manchester United boss Sir Alex Ferguson is proud of the club's successful youth system.

Fergie believes United can be proud of the number of stars developed at Carrington in recent seasons.

He said: "Over the years we've been as good as anyone in the country and probably the best at doing that.

"You look at the way Barcelona have produced players and we're not far off that.

"We've had so many come through down the years and more recently we've had the likes of Danny Welbeck, Tom Cleverley and Rafael come into the first team.

"Then you've got players like Ryan Tunnicliffe, Jesse Lingard and Michael and Will Keane, who are all part of a successful youth team.

"They are progressing very well.

"So we're good at developing young players and we enjoy seeing them come into the first-team squad."
