Alex Ferguson and David Beckham were among those in attendance at the funeral of former Manchester United youth team boss Eric Harrison on Tuesday afternoon.
Harrison, who coached United's famous 'Class of '92', died aged 81 on 13 February.
Beckham, Ryan Giggs, Paul Scholes, Gary and Phil Neville and Nicky Butt worked under Harrison before achieving great success with Ferguson's United, including the treble in 1999.
Ferguson gave a eulogy at the service at Halifax Minster, in which he said: "He was a fantastic coach. There are so many things I could say about him, but the most important thing is he was tough.
"He was making them men. If you wanted to play for Manchester United in the first team in front of 75,000 you needed to be a man, and that is what he gave them.
"It was that toughness that allowed his players to play for Manchester United. When they got to me, I had no fear about their character, because he had formed it."
The former United manager added: "Of course, he improved all his footballers. He did a great job in improving them as footballers. But that wasn't his best job. The best job (is) he made them good human beings. That is what I always remember.
"Everyone who came through in his time at Manchester United were good human beings, and that what they all should be very grateful for, and me in particular."
Along with Ferguson, Beckham, Giggs, Scholes, Gary Neville and Butt, United caretaker boss Ole Gunnar Solskjaer and his assistant Mike Phelan - who worked as Ferguson's number two - were also among around 700 attendees.
In an Instagram post, Beckham said: "Today we say goodbye to a great man... As I look back on what and who made me as a person and as a player, my dad, the Boss and Eric.
"I was stood one day in the cliff training ground in the reception just about to go to Annie Kay's house (my digs) and Neil Webb walks past me and out the door, then Eric walks down the stairs from his office and right up to me and says 'You will replace him in the first team one day'.
"I smiled with excitement but I also thought that's not gonna happen any time soon and then it did. The cliff training ground brings back so many memories as does Littleton road of Eric, 2 laps warm up, 5 ball routine, 12 minute run and the damn heading game which as you can imagine I did not like, but it was all about preparing us for the first team and preparing to play for Sir Alex Ferguson & Manchester United.
"'David stop playing those #*!Y*+E Hollywood balls' will forever be the words that stay in my head but then Eric has me kicking a ball against a wall 60 times with both feet from different distances and that became one of my biggest strengths.
"Ultimately it was The Boss that had that faith in us and took us to the next level but the person that prepared us and we wouldn't have been the players and men we turned out to be was Eric... Thank you Eric and goodbye @manchesterunited"
