French boxer Jean-Marc Mormeck said on Wednesday he is confident that he can beat current WBA/IBF/WBO title holder Wladimir Klitschko in their heavyweight bout on December 10.
"I have overcome every challenge I have set myself in the past," said the veteran fighter, born on the Caribbean island of Guadeloupe.
"I have tried to win every championship belt in the past and now I have the chance to get them. I am strong enough to do it, I am a warrior in the ring," he added during a press conference here in Dusseldorf.
It is in this west German city that 39-year-old Mormeck will face Klitschko, 35, in December.
The youngest of the Klitschko brothers will be returning to the ring for the first time since his comprehensive win against Britain's David Haye in their unification fight in Hamburg in July.
"I don't want to give him any chance, I want to destroy him," said the Ukrainian-born, but German-based, Klitschko of his opponent.
"I might have a glass jaw, but I will knock you out before you even touch it," he added in response to claims made by Mormeck recently.
Klitschko has 56 career wins, including 49 knock-outs, to just three defeats.
Former WBA cruiserweight champion Mormeck is the current North American heavyweight champion. He has a 36-4 record, with 22 knock-outs.
He will be the first Frenchman to dispute a heavyweight title since Lucien Rodriguez in 1983.
