WBC heavyweight champion Vitali Klitschko is having trouble getting an opponent to step up for his next fight. Speaking with Golzka, Klitschko says a proposal for a fight with Tomasz Adamek was turned down, WBA heavyweight champion David Haye is not returning calls and former champion Nikolai Valuev wants too much money to make the fight happen. Vitali is most interested in the "Russian Giant" Valuev. There are issue with making the fight happen.

Vitali says Valuev's co-promoter Don King is standing in the way of the fight with his numerous additional demands during the negotiations. Former champion Shannon Briggs is a possible opponent for October.

"The fight [with Valuev] can't happen because of Don King. We offered Valuev a title shot and $1.5 million dollars. He never earned this much money in the past. Still they continue to ask for more....including money from television [rights]. When has a champion had to persuade the challenger to make a fight? We tried to get David Haye, but heard nothing back. He's scared because he knows the chances of beating a Klitschko are minimal. Tomasz Adamak was sent a proposal and he didn't want the fight. Maybe we will fight with Shannon Briggs. Right now we are talking, but nothing is clear," Klitschko said.
