1973 FA Cup Final Sunderland v Leeds 

Upsets don't come much bigger than this, as Bob Stokoe's second division Sunderland overcame Don Revie's array of international stars beneath the twin towers.
The match itself was decided by two crucial moments: Ian Porterfield swept home the only goal, and then came the moment that defied belief, as Montgomery produced an unbelievable double save that will go down in goalkeeping folklore as well as FA Cup history.

The final whistle prompted delirious celebrations as Bob Stokoe embraced his heroic goalkeeper, and Sunderland became only the second Division Two side to win the Cup since West Bromwich Albion emerged victorious in 1931.

Relive this unforgettable match all over again in this specially produced programme, which also features a rare pre-match interview with Bob Stokoe ahead of the final.
