The manager, who won The FA Cup with Portsmouth in 2008, is desperate to lift the trophy again and is ready for the challenge Owen Coyle's team will present.
"It would be fantastic to win The FA Cup; there's nothing I'd like better than to have a great day at Wembley in the Cup final and to bring it back to White Hart Lane," Harry told his pre-match press conference.
"I would love to win The FA Cup, for sure. It won't be easy, Bolton will come and want to have a real go as well, so it should be a good game."
Despite losses in our last three Premier League fixtures, Harry has seen enough quality in the team to remain unconcerned about results.
"We have had a couple of results that haven't gone our way but the performances have been excellent.
“If we were playing badly you would start to worry but we haven't. I've beaten Manchester United a couple of times in my career but I've never had a team that has played so well against them as we did two weeks ago. I came away wondering how we didn't win, and it was the same at Everton.
“We were just unfortunate. We didn't get the results but I have no problems with the performance. If they had been spread out over the season, you wouldn't have noticed them.”
