Giggs insists part of United's culture is giving their young players an opportunity.
He told the Seattle Times: "I think it's part of Manchester United's history. They've always brought players through, even from the '50s where the Busby Babes were so successful. Right from that stage really, and even before, it's something the fans can relate to: seeing a player grow up through the youth team, seeing them develop from 13 or 14 to the first team and playing for the national team, as well.
"It's something that the manager's very proud of. He wants to see it. But you also have to bring in the quality from around the world that brings the different personalities and different cultures to the club that we've seen over the last five years.
"Also you need that new face, a nucleus of young players that know the history and know the traditions of Manchester United."
