New York - Last November, Tyson Fury pulled off one of the bigger upsets of 2015 when he defeated longtime heavyweight champion Wladimir Klitschko in Germany. Since then, it has been sort of a roller coaster.

Klitschko invoked his rematch clause and at the same time the IBF forced Tyson Fury's hand to vacate, because he refused to face his mandatory due to a contractual obligation to fight Klitschko in a rematch.

That IBF title then came into Charles Martin's hands and then he ultimately lost it to his UK rival Anthony Joshua who is the incumbent heavyweight world champion of that division.

The rematch between Fury and Klitschko has been postponed twice and for now is scheduled for October.

Former world champion Scott Quigg has been in camp with Fury and feels that Klitschko may indeed nab the victory in the rematch.

"I think Klitschko will beat Tyson in the rematch but Tyson's so unpredictable," Quigg told BoxingScene.com. "If the Tyson that shows up in the first match, then he can definitely win again. I want Tyson to win but I have a sneaky feeling that if the rematch does happen - Klitschko will sneak one out."

Though Fury has a reputation for ballooning up after fights, Quigg was in training camp with him and says Fury works just as hard as anyone in the sport.

"Tyson is a real normal guy whether you agree with it or not, he lives his life how he wants to live it. I respect him as a fighter because I used to train with him and saw the way he trains years ago. For a heavyweight he trains like a demon. He might put all this weight on and he may live the wrong life outside of camp but when he's in camp, he does put the work in."
