Chisora: I'll KO Klitschko

Muinich - Vitali Klitschko is ready to retain his world heavyweight boxing title on Saturday against British challenger Dereck Chisora who plans to knock the Ukrainian out in the eighth round.

"Vitali will go KO in the eighth round," Chisora told a news conference on Monday ahead of the World Boxing Council bout. "Vitali used to be a good boxer. But he no longer is."

Chisora, 27, has won 15 of his 17 professional fights while the 40-year-old Klitschko has won 43 of his 45.

Klitschko's manager Bernd Boente said that Munich's Olympic Arena will be sold out with 12 500 fans for the battle between "the young and wild one and the living legend" to be broadcast in 150 countries.

Klitschko's dismissed Chisora's bragging by saying: "I won't give you the belt. You have no chance. Given my form, it will be a tough ordeal for you."
