After almost a quarter of a century managing the Premier League giants, the Scot gave an insight towards what has driven him all these years, as well as how he has toned down his temper to suit footballers of a newer generation, according to reports in the Daily Mail.
Reflecting on his character over the past two decades, Ferguson admitted: "It's my own make up. I like to see myself in all of my players and that is somewhat obsessive. I'm driven. I don't like losing.
"It's been instilled through the years. It becomes a normal situation when players come into the squad and say "I'd better be like the rest or I won't be here too long". It's driven by me, of course.
"When I started at 32, I made sure I wasn't going to fail in this job but I've mellowed. Maybe I've got a short fuse but it goes away quicker", he revealed.
"I switch off quite quickly now. When I was younger, dealing with people away from the game was difficult. At Aberdeen, my assistant Archie Knox and I would find a corner of the pub but someone would come over and voice an opinion, which wouldn't go down well.
"Now I just go straight home and what's really important is the post-match drinks with visiting coaches. We never talk about the game because it's gone. You accept it. It's about dealing with people with the same problems as yourself, the same anxieties, the same feelings of losing", Ferguson admitted.
The Manchester United manager also talked about "the hairdryer" treatment that he has reserved for players who incurred his ire over the years, and whether or not he has damaged stars with his treatment, especially in light of a rumoured bust-up with David Beckham.
"I hope not," replied Ferguson. "There's a lot of myth attached to that. In training there's nothing but praise for every player. Nothing but positives.
"Where David and other people are coming from is how I react to defeat, which is not easy for me. I don't think I should change. I don't like people who change. I think you should stick by your nature. But after it's over it's over. I never go back. Tomorrow is another day for me.
"The hairdryer is part of the myth and the circus. It's completely exaggerated, like throwing the tea cups.
"But I'm a confrontational character and I don't like people arguing back to me. I think that's where the hairdryer treatment came from", he concluded.
