The Welshman retains a place in the hearts of United fans, perhaps for one reason more than any other. With only minutes left in the 1991 European Cup Winners’ Cup final, he denied Barcelona an equaliser, clearing Michael Laudrup’s effort off the line.
The ex-Wales international rose through the club's junior ranks to make 245 first-team appearances, so his latest post - as a coach to the under-15 Academy side - seems highly appropriate. Blackmore took time out to answer your questions about that, and about his successful playing career...
Do you enjoy coaching kids, and do you plan to manage again? (Nathan Scholes)
I have been back at United for 12 months and yes, I enjoy working with the kids. I was a youngster here and know what the lads go through. I’ve been in charge of Wales schoolboys and under-21s and I've managed Bangor City. Maybe I will go back into management one day, but this suits me now.
Who was the best player at United in your day? (Nutterfield)
I’ll go for Ryan Giggs, because of what he has achieved and is still doing at the age of 36. I try to judge footballers in terms of not wanting to play against them, and Ryan was always a nightmare to train or play against. He was so elusive and one of the hardest players to mark that I have ever faced.
What was playing for Sir Alex like? (Reinhard21Chris)

What a lot of people don’t realise is that off the field he is totally different and like a parent, a big dad, to the players.
Was being versatile a help or hindrance? (Paul Taylor)
It could work both ways. I may not have played so many games had I played in one position, yet on the other side of the coin I didn’t have a regular place. I enjoyed being versatile and the challenges of playing in different positions. I was everywhere except keeper, I think.
You had an explosive shot, but what was your best goal? (TimmyM)
I scored lots for the Reserves
