Manchester United chief David Gill feels Sir Alex Ferguson's legacy will be his success with young players.
Gill says Ferguson has always made it a priority for the club to develop their own talent.
He told MUTV: "Alex's legacy to United is to my mind very clear - delivering an unprecedented period of success in the Manchester United way. By that, I mean attractive football using young players - both homegrown and buying players when necessary like Ronaldo and Rooney, but actually developing our own players.
"That record is there for everyone to see and that legacy is very clear also. Within that, he's made sure he's cemented United's position as one of the top clubs in world football. We're very well respected clearly in this country and around the world, you only have to see our following there on tour in America and Asia, plus in Europe when you speak to any other club.
"United are rightly held in very high esteem down in no small measure to what Alex has achieved in the last 25 years."
