1979–80 West Ham United F.C. season

A Second Division West Ham side beat an Arsenal side that had been in the previous two FA Cup Finals, had just finished 4th in the First Division and who were overwhelming favourites to win. Winning the Cup for the third time, West Ham manager John Lyall tactically outsmarted his Arsenal counterpart Terry Neill by paying a 4–5–1 system, stifling Arsenal's creative midfield that included future West Ham signing Liam Brady and the steely Brian Talbot. The only goal in the 1–0 victory was scored by Trevor Brooking.
