Wing-half Crowther was in the Aston Villa team who beat United 2–1 to win the FA Cup in 1957 and, the following year, he joined a Reds team that had been decimated in the Munich air disaster, just in time to make his debut in the FA Cup against Sheffield Wednesday.
Crowther would normally have been cup-tied, having already played for Villa in that 1957/58 season, but the FA gave United special dispensation to field him. The Reds won the match and went on to reach the final, in which Crowther played but finished on the losing side as Bolton Wanderers triumphed 2-0.
The Midlands-born player, who appeared for England at Under-23 level, left Old Trafford for Chelsea in December 1958, having made 20 appearances in total for United, and later had short spells with Brighton & Hove Albion and non-league sides Hednesford Town and Rugby Town.
Staff at Manchester United extend sincere condolences to Stan's family and friends at this difficult time.
