If Anthony Mundine pulls this off, people will have to start calling him the black Houdini.

That's the belief of the former rugby league star, who takes on bitter rival Danny Green in a highly-anticipated boxing rematch on February 3.

The 43-year-old Mundine will likely be giving up as much as 13 kilograms in weight to Green by the time the pair step into the ring at Adelaide Oval.

"I never really thought it was going to happen to be honest. He went up in weight, to cruiser-weight," Mundine told reporters in Sydney on Friday. "He fought some big men, pretty much heavyweights. Antonio Tarver is now a heavyweight, the cruiser-weight champion.

"This is some David-Goliath stuff, what's going on right here. If I can pull this off, you all gotta call me the black Houdini or something because this is something that's not supposed to happen. This don't come around, not even in generations."

The fight is set at a catch-weight limit of 83kg [183-pounds], a far cry from the 76.2kg super middleweight limit the duo faced off in their previous meeting in 2006 which Mundine won.

Mundine was a underdog then and he was quick to seize the status again.

"The weight advantage is a massive deal. For people that don't know boxing, guys that give away half a kilo or a kilo get fined massive money. It's big just giving away one kilo," he said.

"I'm coming up four divisions. We ain't fighting at cruiser-weight, we're fighting at Danny weight, what Danny wanted to fight at. So I'm leaving him no excuse. All the pressure's on him.

"I should be 100-1 underdog, for real. Thirteen kilos, man, my last fight was 69.5 I come in at. We're fighting at 83. I won't even make 83. But I'll be a strong, fit, ready 79-80kg."

With both boxers believed to pocket $10 million each for the re-match, Mundine advised his nemesis to be thankful just for the opportunity to exact some revenge.

"To Danny, be humble man. Be gracious. I'm giving you another pay day," he said.

"Be gracious that I made your career. Without me, you'd be nobody. You'd still be fighting in RSLs. At the end of the fight, thank me for what I done for the sport and your career."
