Arsene Wenger is still haunted by the game which was the catalyst for Manchester United ’ s greatest ever achievement . It was in 1999 , another FA Cup tie , a semi-final . It was at Villa Park , with 90 minutes of a replay having failed to separate the two teams that then dominated English football in that era . United were down to 10 men and Dennis Bergkamp had missed a penalty for Arsenal in the final minute of normal time with the game locked at 1-1 . Arsene Wenger looks on dejectedly after losing the FA Cup semi-final replay to Manchester United in 1999 . Dennis Bergkamp ( right ) missed a penalty in that game in United 's treble winning season . Ryan Giggs ( right ) struck United 's winner with a sensational solo effort to send them through to the final . Then on 109 minutes , Patrick Vieira misplaced a pass , Ryan Giggs picked up the ball in his own half and set off on a run which would end up in him revealing an alarming amount of chest hair after scoring one of the great goals in the history of the tournament . In Wenger ’ s mind , it tipped the balance in the title race and provided the foundation for United to achieve an unprecedented treble of FA Cup , Premier League and Champions League . ‘ I can still hear the shouts of that team , having won , ’ said Wenger . ‘ They couldn ’ t believe it because they were down to 10 men . And I think that put them in a state of euphoria . In the same way , they won the title — just . ‘ I saw that goal again when Giggs retired . I think that goal won them the treble because , if Bergkamp scores , I think the game is over . It was a trauma for us and a positive for them . That goal was certainly what decided their season. ’ Wenger still remembers the details of the title run in , saying : ‘ They played at Blackburn and we lost at Leeds in the last minute , when Nigel Winterburn was kicked off [ the pitch ] . Jimmy Floyd-Hasselbaink scored at the far post and Kaba Diawara hit the bar twice . After that , they won the Champions League final in the last minutes — 1999 was a miracle year for them. ’ Bergkamp recalls missing the penalty in his book and admitted it bothered him for a while after the game . Giggs ( second left ) will now take on Wenger from the dugout as an assistant to Louis van Gaal . Wenger will be hoping to avenge the defeat by beating United in Monday 's FA Cup quarter-final . Bergkamp in his book , Stillness And Speed , said : ‘ I still took the odd [ penalty ] without problems , without hesitation and without missing . But that miss did bother me for quite a while and next season Thierry Henry became our penalty taker. ’ Ray Parlour , who was interviewed for the same book , said : ‘ In those days it was only us and United . Dennis , if he scores that penalty , we win the double because ... their heads would have gone down in the league. ’ As for Monday , Wenger said : ‘ Let ’ s not consider Man United . Let ’ s focus on our performance . They play at home where they feel confident . So , to compensate that we have to put more effort in and produce a really top-level performance . ’
