Trainer Peter Fury has warned unified world heavyweight champion Wladimir Klitschko that Tyson Fury will be in the shape of his life when the pair meet in Dusseldorf on October 24.
The 39-year-old Ukrainian (64-3 53KOs) holds the WBO, WBA, IBF and IBO belts and has not lost since 2004, and was last in action in April when beating Bryant Jennings at Madison Square Garden via unanimous decision.
Fury, 26, is the mandatory challenger for Klitschko's WBO belt and with an unbeaten record of 24-0 (18KOs) heading in to the clash, his uncle and trainer Peter dismissed comparisons with previous Klitschko opponent Mariusz Wach and insisted this represents Klitschko's toughest test to date.
"It's definitely Wladimir's toughest test to date. Regardless of what people say, it is. Mariusz Wach is levels below Tyson. He's got nowhere near the boxing skill, movement or speed. Wach is a different ball game altogether. It's like preparing a donkey against a racehorse," he said.
"You're going to see a whole new Tyson, different to how he's ever performed to before. He's got to raise his levels 10-fold. That's what he'll need to do to beat Klitschko and that's what he will be doing.
"It's his third week in camp. Everything's going well and he's dropped over 35lbs in body weight already. He's going to be totally lean and he'll be in the best shape of his whole career.
"This is what he's always dreamed of, what he's worked for all his life. He'll be in the best shape physically and mentally. It's a fight he knows he can win so he's looking to bring all those belts back.
"We're going to do the camp in Ireland. We're going to Ireland this time because that's where our ancestors are from and it's nice to bring Ireland in to be a part of this world title shot."
Reflecting on Klitschko's past victories, Peter Fury added: "I thought Klitschko did well [against Jennings] but it was a boring fight to watch. It wasn't a good fight. Styles make fights and Jennings is better than people think but it wasn't a good thing to watch.
"David Haye was afraid of Klitschko and showed that. There's no fear here - Tyson loves to fight and wants to get in there. It's a proper even fight. Haye is a cruiserweight-cum-heavyweight whereas this is a real heavyweight fight.
"There are going to be people very excited in the build-up to this fight. I think people have paid for the press conference!"
Peter Fury also confirmed that Tyson's cousin, heavyweight prospect Hughie Fury (15-0 8KOs), will fight on the undercard.
