Klitschko, 39, will defend his IBF, WBA and IBO titles against Britain’s Fury, 27, in Duesseldorf having last tasted defeat more than a decade ago.

This is the second time the fight has been scheduled to take place after the original date in October was cancelled due to Klitschko’s calf injury.

Fury has won all of his 24 fights to date with 18 knockouts and has vowed to not only usurp Klitschko, but also highlight the champion’s weaknesses.

“I think this might be one of my easiest fights,” boasted Manchester-born Fury in Tuesday’s press conference.

“I know that sounds crazy, because he’s a Super champion, but I see so many chinks in his armour.

“There is nothing he does which makes me think I won’t beat him.

“I can expose what he doesn’t do very well and you’ll see what I’m talking about on Saturday night.

“I’m not going to say too much today as I don’t want to scare him off.

“I’m coming very fast for you, Wlad. Old guy, young guy. Old champion, new champion. Enough said. Amen,” added Fury ahead of the bout at Duesseldorf’s Esprit Arena with 42,000 tickets sold.

Klitschko has heard such bold statements before from previous challengers, many of whom then became one of his 53 knockouts in 64 wins.

Britain’s David Haye labelled the champion a ‘large, slow robot from the Ukraine’ before losing on points in Hamburg in July 2011.

The last of Klitschko’s three defeats was back in 2004.

“There have been many fighters I’ve faced, this time I face a guy whose young, a real challenge,” said Klitschko.

“It’s going to be a great night.

Having previously said the eccentric Fury has “screws loose,” Klitschko said he will give the Mancunian his own brand of “therapy” in the ring.

“I believe he is insane,” said Klitschko, who is nicknamed ‘Dr. Steelhammer’, in an interview with Die Welt.

“He’s a patient who urgently needs therapy.

“And the boxing ring, the fight, is the best form of therapy.

“I’m a doctor and I’ll rescue you.”

Fury stirred up controversy earlier on Tuesday in a BBC interview by claiming boxing has a “big problem” with doping.

He suggested that the sport should tackle the issue by legalising banned substances.

The British fighter said he hopes the World Anti-Doping Agency (WADA) has tested both boxers stringently.

“WADA have tested me very regularly, sometimes three times in a month,” said Fury in Duesseldorf.

“Hopefully he’ll have been the same.”

Klitschko dismissed the issue, stating: “I’ve been tested a lot, over a quarter of a century.”

There is an issue with Fury’s gloves for the fight which sparked a brief war-of-words in the press conference between the fighters’ managers.

Fury is training with different gloves after his thumbs were damaged by a faulty pair and the manufacturers are rushing a replacement, specially for the fight, to Germany.

“It’s a health and safety issue, the gloves should arrive before Saturday,” said Fury’s coach and uncle Peter.
