As George Kambosos Jr. prepares to face Lee Selby on Saturday, Oct. 31, the Australian has declared he has been training "like a man possessed."
The pair will meet for an IBF lightweight title final eliminator at the end of the month on the undercard for the Oleksandr Usyk vs. Dereck Chisora fight.
Kambosos (18-0, 10 KOs) is undefeated, and a win would make him the mandatory challenger for unified lightweight champion Teofimo Lopez Jr., who dismantled Vasiliy Lomachenko by a unanimous decision victory on Saturday in Las Vegas.
Kambosos made himself known as a potential future champion when he beat former world champion Mickey Bey at Madison Square Garden, and he will next fight Welsh boxer Selby, himself a former champion with the IBF featherweight belt.
Kambosos said: “Beating Lee Selby means everything to me.
"I’m hungry, focused and have trained like a man possessed to handle business on October 31st. This is a young man's sport and Lopez proved that against Lomachenko when he became the unified lightweight world champion, and I will prove it once again against Lee Selby.
"This hungry young lion will become mandatory, that is my complete focus, this is why I have sacrificed so much and then you best believe that 'Ferocious Kambosos' will be primed and ready to take all the belts off another hungry, young lion in Teofimo Lopez. Let’s see who the real king of the jungle is."
Selby (28-2, 9 KOs) defeated Scottish veteran Ricky Burns at the O2 in London last October, and this fight could give him the chance to claim another belt.
"He's very confident in himself," said Selby. "If you listened to him talk you'd think he's the next Muhammad Ali — which he's not. Looking at his record, it's difficult to gauge how good he really is. His best win came against Mickey Bey when he was past his best at 36 and inactive. The rest of his record is padded.
"This fight has been a long time coming and I'm glad we're just over a week away now. I’m one step away from a shot at the IBF lightweight world title and my dream of becoming Wales' first ever two-weight world champion."
Kambosos vs. Selby will be on Sky Sports Box Office in the U.K. and on DAZN in the U.S. and other DAZN regions.
