Manchester United had been invited by Glentoran FC to play a match at the Oval to promote the Ulster '71 Festival. However, ex-Manchester United manager, Sir Matt Busby was unable to confirm his club's participation. Consequently, their Division One rivals, Leeds United, played in a match which resulted in a famous 3-1 victory to Glentoran.

Manchester United was to have been offered £3,500 to field a full team including George Best 'the idol of Belfast'.  Leeds United would eventually be paid £4,000 for the match that took place on 5th May 1971.
