The Scot retired at the end of the 2012-13 season after guiding the Red Devils to their 13th Premier League title of his tenure, although he has revealed that at times he does miss the day-to-day challenges of managing in the top flight.
Ferguson told MUTV: "I thought when I retired I wasn't going to look back in terms of my role as a manager. What I didn't do as a manager all my life was look back at things we'd achieved.
"I never did that, ever, because I didn't think it was important. I always thought tomorrow was the most important day. That way there was always a challenge for myself. Win something – it didn't matter, it was gone. Are we going to win something again?
"That was my attitude as a football manager. Obviously I miss the players and I miss the staff at Carrington, fantastic staff. The camaraderie."
Ferguson managed the Red Devils for 27 years.
