Sir Alex Ferguson read a eulogy and David Beckham was also among those in attendance as the funeral of former Manchester United youth team boss Eric Harrison took place in Halifax on Tuesday afternoon.
Harrison, who coached United's famous 'Class of '92', died aged 81 on February 13. 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.
In his eulogy at the service at Halifax Minster, Ferguson 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. It was that toughness that allowed these 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 (was) 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's what they all should be very grateful for, and me in particular."
As well as the eventual treble-winners, Harrison, who was diagnosed with dementia a few years ago, oversaw the development of a number of other youngsters who went on to have high-profile careers, including Mark Hughes.
He was brought to United from Everton by then Red Devils boss Ron Atkinson in 1981 to work as a youth team manager and spent 27 years with the Old Trafford outfit. He also had a stint working as Wales assistant boss under Hughes.
Harrison was awarded an MBE for services to football just over 12 months ago.
