Vladimir wants Haye fight

"I am ready to fight against David Haye anywhere in this world," Klitschko said. "He (Haye) just needs to make the next step. Sign the contract, get in the ring and get the fight.

"I have no respect for this man because he is nothing but a little dog who just runs away when the big dog turns around.

"It's not about the money and the business, it's about pride (for him). But I think he owes it to the fans."

Vladimir, the younger of heavyweight boxing's dominant Klitschko siblings, holds the WBO, IBF and IBO belts. Vitali, his brother, is the WBC champion and Haye holds the WBA title.

The Klitschkos will not fight each other, meaning that most boxing followers, and broadcasters, hope for a Vladimir Klitschko-Haye showdown.

Speaking at the Commerzbank Arena in Frankfurt, where he will fight Nigerian Samuel Peter on September 11, Klitschko (54-3, 48KO) added: "Right now (Haye) is just not important to me."

Haye (24-1, 22KO) was due to fight Klitschko last June but withdrew because of injury.

Klitschko said his fight with Peter, made after original opponent Alexander Povetkin pulled out, would be tough, but that the Nigerian's similar style and size meant he did not have to adjust his preparations.

Klitschko beat Peter on points in 2005.
