Arsenal boss Arsene Wenger admits he's still haunted by Ryan Giggs' winner for Manchester United in the 1999 FA Cup semifinal.

The Gunners go to United tomorrow night for the Cup quarterfinal.

"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."
