Tyson Fury insists he believes in his own ability to stun David Haye in their eagerly-anticipated heavyweight clash on September 28th, live on Sky Sports Box Office.
The Haymaker labelled Fury as 'deluded' and having 'a screw loose' for claiming he was the greatest boxer ever, but the unbeaten 25-year-old insists that hype is just confidence in his own ability.
The 32-year-old Haye has more experience of the build-up to a big fight, but Fury says he is in the shape of his life after a tough training camp in Belgium.
And, speaking to Sky Sports News, Fury agreed that he was deluded, but only so much in that he truly believes he can beat Haye on September 28.
"I probably have got a screw loose," said Fury. "I think all boxers have a screw loose because we wouldn't get punched in the face for a living if we didn't, we'd be doing something else using our brains a bit more.
"And I might be a bit deluded because I believe in my own hype - everything I say I believe it 100 per cent
"If I said to you I could bend that radiator in half and I meant it, I'd believe that I could, so if that's deluded, then that's what I am because I believe in my ability."
Haye has been having some tough sparring in the build-up, but Fury says that everything is against him and believes the Londoner will be in for a tough night right from the start.
"I hope they've been training him very hard and preparing him well because he's going to need it," Fury added.
"Everything is against him, his age, his size, his speed - everything. It's an uphill battle from round one so he's going to need all the preparation he can get."
David Haye's heavyweight clash with Tyson Fury is live on Sky Sports Box Office on Saturday, September 28. Programme begins at 8pm.
