When preparing to fight a Klitschko brother, training camp is always difficult. Most opponents have trouble finding the right kind of sparring. There are only so many heavyweights that comes close, physically, to the Klitschko brothers. When a heavyweight begins camp for a Klitschko fight, there are always fears about the training.

Unbeaten British heavyweight Derek Chisora has confirmed some of the lingering talk about his training camp. He faces WBO/IBO/IBF champion Wladimir Klitschko on December 11 in Germany. Wladimir is close to 6'7 and has an 81-inch reach, which is a huge advantage over Chisora, who is close to 6'2 and has a 74-inch reach.

There have been rumors about Chisora having issues in training camp. He confirmed those rumors to Sky Sports News. Like past Klitschko opponents, Chisora is having trouble finding sparring partners and admits that he's not getting enough sparring partners in camp.

"I haven't been getting enough sparring partners," Chisora said. "I want to pay good money but they won't come up here, they're giving me all talk."
