Alan Sunderland's most famous moment came in the 1979 FA Cup Final; Arsenal had gone 2–0 up against Manchester United, with goals from Brian Talbot and Frank Stapleton, and looked set for victory with only five minutes remaining. However, United scored twice in three minutes, with goals from Gordon McQueen and Sammy McIlroy, and extra time loomed. In the very last minute of the match, however, Arsenal pushed forward in a desperate counter-attack; Liam Brady fed Graham Rix on the left wing, and his cross was converted by Sunderland at the far post to make the score 3–2, and win Arsenal the cup.
