Manchester United chief David Gill says it's crucial the club continues to bring through young players.
He says it is vital the club do not lose track of their roots and continue to develop players such as Ryan Giggs, Paul Scholes and Gary Neville.
"I don't think we'd ever field a team full of foreigners," he told the National newspaper.
"When those great players, who have been part of the team for 15-odd years retire, others will step up.
"Hopefully we'll have players coming through the academy who understand what being a United player means."
