After WBO/IBF heavyweight champion Wladimir Klitschko retained his titles with a stoppage of Ruslan Chagaev in Gelsenkirchen, Germany, he had some hard words for David Haye. The British fighter was scheduled to meet Klitschko before pulling out with a back injury. Wladimir will not forget about Haye and his months of trash talk. He vowed to knock him out in the future. Wladimir will likely make a mandatory defense against undefeated Alexander Povetkin in September.

"I am very upset about David Haye, he has a big, bad and dirty mouth, I can not rely on this man, he is immature as a fighter and immature as a person," Klitschko fumed to Sky Sports. "I missed a fight in April to accommodate him, he couldn't deliver Chelsea (Stamford Bridge), so we moved the fight here.

"There is no blame on him physically, a fighter's health is important and boxers get injured. But he kept telling journalists that he needed two more weeks to recover, then he needed three, four weeks, I just kept hearing he needed more and more time. If he wants to fight me now, no problem, get in frigging line, I will knock him out in the 12th."

Wladimir also had some words for WBA champion Nikolai Valuev. He says the seven-foot giant turned down the opportunity to fight him when Haye withdrew. Chagaev jumped at the chance.

"Nikolai Valuev was the first boxer we asked when Haye pulled out and he was also the first fighter who said 'no'," said Klitschko. "Ruslan Chagaev didn't take too long to accept the fight and respect to him for that. I will come back to box here and I also want to box at Madison Square Garden again.

"The Klitschko brothers have almost all the belts and I am just enjoying the process, I am not thinking of my legacy, I just want to find the best fighter in the world and beat him."
