Ferguson is regarded the greatest manager ever in English Football having led Manchester United to enormous success.
He took a struggling Manchester United in 1986 and made them one of the greatest clubs in Europe.
The Scottish led the Red Devils to 13 Premier League titles, two Champions League trophies, five FA Cups, four League Cups and countless more titles.
Ferguson stepped down as Manchester United head coach after the 2012/2013 season and the club have not been the same as far as winning trophies is concerned.
Speaking in a QA session for his upcoming documentary ‘Sir Alex Ferguson: Never Give In’, the 79-year-old has revealed his regret at dis-assembling one of his finest Manchester United squads at the beginning of the Premier League era.
“In terms of the regrets, the 1994 team I had, the back four all seemed to grow old together, and that’s a terrible thing to happen to the manager because these guys were fantastic for me,” he said.
“Paul Parker, Steve Bruce, Gary Pallister, Denis Irwin: Fantastic players. They gave me nine or 10 years and the evidence is always on the football field. They don’t see it. I see it.
“The problem for me is ‘what do I do about it?’. I managed to organize a move for them, and they did well out of it, but telling them is very, very difficult.”
Ferguson added: “The same when having to let young players go. The process was the youth coach and the welfare chap would come in with the player you’re going to let go.
“Maybe he’s only 17, 18 years of age. The way we’d explain it is we’d try and get him a team. We’d try and get him a club and ‘we’re sorry we’re having to do this’. That’s terrible.
“That is the worst thing, having to let a young player go. All his ambitions and hopes and desires are about playing for Manchester United in front of 75,000 people and going to Wembley in a final.
“That’s the ambition of every young kid that comes to Manchester United, and when you take that away from him, it’s a sore, sore thing. So I hated that. I hated that.”
