David Haye says the high quality of his sparring partners is bad news for British heavyweight opponent Tyson Fury ahead of their Sky Sports Box Office clash on September 28.
Fury will put his unbeaten record on the line in front of his home fans in Manchester against former WBA world champion Haye.
The pair are deeply embroiled in a war of words which has forced the British boxing public to sit up and take notice in an eagerly-awaited contest.
Haye, who has 26 wins and two losses on his record, will go into the clash as a favourite despite giving up six inches in height and seven inches in reach to his 25-year-old opponent.
The 32-year-old Londoner defeated Russian giant Nikolay Valuev in November 2009 to claim the WBA belt but lost a world unification attempt to Ukraine IBF and WBO heavyweight king Wladimir Klitschko in July 2011.
Haye is confident his stable of sparring partners will have him more than ready to face Fury and said: "I have no doubt whatsoever that the guys brought over for me to spar would do a number on Fury in a fight.
"That's what has made this camp so great. Rather than bringing over the typical sparring partners, guys used to just taking punishment, I have brought over a load of top-10 heavyweights, some of them unbeaten, with lots of ambition and pride.
"I have also brought over big, big punchers."
Among Haye's sparring partners are unbeaten American Deontay Wilder and Pole Mariusz Wach, who lost on points to current WBA, IBF and WBO king Wladimir Klitschko just last year.
Ukrainian Alexander Dimitrenko and Sheffield's Richard Towers have also been part of the Londoner's camp and Haye believes any one of them would give Fury major problems.
"Wilder punches about as hard as anybody in the division right now, and he'd be nailed-on to spark Fury in a fight," continued Haye. "One shot from Deontay would do the trick.
"Wach is one of the toughest men I've ever shared a ring with. You couldn't even budge him with a baseball bat. Some nights I've wanted to try.
"Dimitrenko is a better schooled version of Fury, and Towers has been great for me, because he brings a lot of unorthodox moves to the table and has a long, fast and accurate jab.
"Each of them would make Fury look silly in a fight. Wilder would spark him, Wach would maul him from pillar to post, and Towers and Dimitrenko would outbox him round after round.
"Now imagine what I'm going to do with him."
