The FA Cup fourth round has delivered a host of thrilling ties - BBC Sport takes a look back at some of the most memorable in this one-hour special. Despite beating Swansea in the third round, non-league Havant & Waterlooville were given no chance of claiming victory at Liverpool in the fourth. However, they led twice in the first half of their 2008 tie at Anfield - eventually losing 5-2 in a breathless encounter. The clock will also be wound back to the 1980s, with the spotlight on two famous cup upsets from that decade - York City's 1-0 win over Arsenal and Port Vale's 2-1 victory against Tottenham.
