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...

You had an explosive shot, but what was your best goal? (TimmyM)
