April 11, 1999: FA Cup semi-final, Villa Park - The two heavy-weights of English football began the first chapter of the epic with a high drama throughout 120 pulsating minutes. United felt cheated when Roy Keane had a goal ruled out for offside. Ryan Giggs skipped past Lee Dixon in the 38th minute and crossed towards Dwight Yorke. He nodded the ball back to Keane who rifled in from 12 yards, but the goal was disallowed because Yorke was judged to be offside. Despite the sending-off of Arsenal defender Nelson Vivas, the Gunners held on to force a replay.


ARSENAL 1 - MANCHESTER UNITED 2 (after extra-time)

April 14, 1999: FA Cup semi-final replay, Villa Park - A game which anyone who was there will never forget. After a tense goalless first encounter, David Beckham put United in front during the first half, only for Dennis Bergkamp to level. Then it began to get interesting. Roy Keane was red-carded, giving Arsenal the edge. And when the Gunners were awarded a last-minute penalty, victory looked assured. But Peter Schmeichel turned Bergkamp's effort wide to send the game into extra-time, where Ryan Giggs took centre stage. Picking up the ball in his own half, the Welsh winger evaded four Arsenal defenders on his glory surge into the Gunners box, then unleashed an unstoppable near post shot which left David Seaman beaten. United went on to beat Newcastle in the final, clinching the second leg of their unprecedented Treble.
