|Sir Alexander Matthew "Matt" Busby, CBE, KCSG (26 May 1909 – 20 January 1994) was a Scottish football player and manager, most noted for managing Manchester United between 1945 and 1969 and again for the second half of the 1970–1971 season. He is the longest serving manager in the history of Manchester United, ahead of Sir Alex Ferguson, although the latter has overseen more matches as manager.|
Before going into management, Busby was a player for two of Manchester United's greatest rivals, Manchester City and Liverpool. During his time at City, Busby played in three FA Cup Finals, winning one of them. After his playing career was interrupted by the Second World War, Busby was offered the job of assistant coach at Liverpool, but they were unwilling to give him the control over the team that he wanted and he took the vacant manager's job at Manchester United instead.
