IBF/WBO/IBO world heavyweight champion Wladimir Klitschko is very determined to punish his next challenger, undefeated Commonwealth and British champion Dereck Chisora. Klitschko will defend the title against Chisora at the SAP Arena in Mannheim, Germany, on December 11.

Klitschko is not overlooking his inexperienced opponent. He says Chisora is very dangerous due to his punching power and untested abilities. Because of Chisora's recent taunts, Klitschko wants to break his will in the ring. He says Chisora is a much better opponent than WBA heavyweight champion David Haye.

“Chisora is very young, determined and does not know how far he can go. That is an advantage for him and dangerous to me. I will teach him a lesson in the ring – mentally, psychologically and physically. For me, Chisora is much better than David Haye and much more complicated to box," Klitschko said.
