The biggest upset in the history of the FA Cup finals came in 1973 when Second Division Sunderland overcame the skill and strength of Leeds United with a goal from Ian Porterfield and a famous save from Jim Montgomery. Sunderland's Cup run this year has seen them score victories over First Division teams West Ham, Chelsea and Norwich. It's now Liverpool's turn to face the 1992 giant-killers in an intriguing Wembley clash. Will John Byrne, the Sunderland striker who has scored in every round of the Cup so far, add a Wembley goal to his tally? Or will the inconsistent Liverpool team that struggled to beat Portsmouth in the semi-finals rise to the occasion?
