Fury would consider retirement if he loses

Tyson Fury has reiterated that he will consider retiring if he fails to defeat world heavyweight champion Wladimir Klitschko.

Fury challenges for the Ukrainian's WBA Super, WBO and IBF belts at the ESPRIT Arena in Dusseldorf on Saturday, aiming to become only the eighth British heavyweight to claim world title glory.  

However, the undefeated 27-year-old (24-0-KO18), who weighed in just one pound heavier that the champion, claims he may call time on his career if he is unable to overcome Klitschko (67-3-KO53) in what will be his first world title fight. 

"If I lose on Saturday, I'm a fraud," he said. 

"I won't be the champion I think I am. It would mean I'm no good. Simple. If I can't beat Wlad, it means I'm no good. And I'll be the first person to say that.

"I'd think about retiring, for sure. Because make no mistake, there's nobody out there other than Wlad that's any good. I think Wlad could beat the rest of them out there.

"It is what it is. if I don't beat him then I'm obviously no good so I'll think about doing nothing and just put my feet up."

Fury, who weighed in one pound heavier than Klitschko at 247lbs on Friday, is by no means expecting his career to end in Germany. 

"I think it's going to be really easy to be honest," he said. "One of my easiest fights.

"It's just another fight for me. They're all must-wins. This fight is no more important than my last one or the one before that because every one is just a piece in a jigsaw puzzle and if I hadn't won those ones before I wouldn't be in this position.

"To me it's just a boxing fight. Two men, two pairs of gloves. That's it. We'll go at it and may the best man win. I have no hard feelings towards Wladimir, and I hope he performs to the best of his ability."

Klitschko says he is expecting his biggest challenge since fighting David Haye in 2011, when he claimed a majority points decision victory. 

"I would say so," he said. "I had some challenging fights before that and then again with Haye.

"There is a lot of noise, there is a lot of tension and pressure (against these fighters).

"But pressure is actually a positive thing, you perform better under pressure."
