A tough-tackling midfielder blessed with phenomenal passing and vision, Paddy Crerand joined United from Celtic on 6 February 1963, the fifth anniversary of the Munich air disaster.
The Scottish international was an integral part of United's 1968 European Cup-winning team, and his legendary status among supporters was guaranteed long before the end of an epic 397-game Reds career. Paddy's staunch support of the club has also helped his cause, and he regularly commentated on the Reds for radio stations throughout the 1980s and 1990s, before joining MUTV in 1998.
Crerand continues to co-commentate for the channel for all first team matches and occasionally Reserves games, while he also fronts the Paddy Crerand phone-in show, where callers get to pick his brains about all things United.
"You get more emotionally involved with the club when you've stopped playing," admits the Scot. "Football's an emotional game and I think this is a club built on emotion, going back to Munich, so there have been some great occasions to remember.
"For me, and I think a lot of people would agree with me, the outstanding memory is the 1984 win over Barcelona when we were 2-0 down from the first leg and won 3-0. It was a fantastically emotional night, one of the great, great nights here at Old Trafford.
"More recently you have Michael Owen's winner against Manchester City. That was an overwhelming occasion for me as well, because it's City and it's the local derby, but the atmosphere against Barcelona was incredible."
