Alexander Dimitrenko (29-0, 19KOs) was not impressed by what he saw over the weekend. On Saturday night in Germany, Alexander Povetkin (17-0, 12KOs) won a ten round unanimous decision over Jason Estrada. Dimitrenko and Povetkin are up and coming heavyweights for rival promotional companies in Germany. Dimitrenko with Universum and Povetkin with Sauerland Event.

And they are also in line to fight IBF/WBO heavyweight champion Wladimir Klitschko. Povetkin is the IBF mandatory and Dimitrenko is ranked at number one by the WBO.

Dimitrenko wants Povetkin to accept his challenge - a showdown between the two top contenders and the winner secures the right to fight Wladimir.

"Povetkin did not convince me in that fight. It wasn't a good achievment [for him]. A lot of other people saw the same thing. Simply, that wasn't a world class level [performance]. He needs train more if he wants to fight for a world championship. From the start he had problems and the opponent was a nobody and 6'1. Povetkin should fight bigger opponents, like me," Dimitrenko said.

The EBU heavyweight title is vacant and the organization wants the two heavyweights to fight for the title.

"I hope he doesn't avoid me. The EBU prepared the fight. A person has to convince [people] in the ring. He has the possibility [to do this] against me. I am ready," Dimitrenko said.
