Former cruiserweight champion Jean Marc Mormeck (36-4, 22KOs) had a good laugh when he heard Wladimir Klitschko compared him to heavyweight great Mike Tyson. Although the two of them are similar in size, Mormeck is realistic and doesn't believe the comparison fits.

"I'm not Mike Tyson, though sometimes it's a good PR stunt. I have neither the explosiveness nor the punch," said Mormeck.

On Saturday night in Duesseldorf, Mormeck will challenge Klitschko for the IBO/WBO/WBA/IBF titles. Klitschko is 6 1/2 inches taller, four years younger, has a 7-inch reach advantage and won his last 14 fights.

Mormeck admits that most people don't give him a shot at lasting five rounds, let alone winning.

"I can imagine what the odds will look like for me against Wladimir Klitschko," Mormeck said. "But I know my skills. I had [David] Haye on the canvas and shortly before a knock out which Klitschko could not do. What I missed out against Haye I will now do with him."
