In-rehab Anthony Mundine has declared he should be ready to fight Danny Green early next year and is willing to do so significantly lighter than his bitter arch-rival.
A big-money rematch has been spoken of on and off ever since Mundine beat Green in a unanimous points decision in Sydney 10 years ago.
Rather than get back in the ring, the pair have quarrelled over terms of a potential multi-million-dollar bout.
But Mundine said they were now deep in negotiations following his successful hip surgery four months ago.
And though the 40-year-old Aboriginal Australian would still love the bout to be held at the sacred indigenous site of Uluru, he said he'd fight Green anywhere for "the biggest payday out there".
"Hopefully it's going to be sooner rather than later," Mundine told AAP in Sydney at a basketball clinic for disadvantaged children.
"Next year. It's all about rehab and getting my body right.
"I reckon another three months I'll be right and then just prepare for the fight. I need six months to prepare to get my body right."
Mundine has previously said he'd be prepared to fight at catchweight set at 83kg - meaning he would have to gain about 10kg while Green would have to drop around 6kg - but only if `The Man' gets a 60-40 share of the purse.
However he appeared to have softened his stance, only saying the money "fluctuates".
"He's going to have the advantage because I'll give away all that weight," said Mundine, who had recently been keen to fight boom Brisbane boxer Jeff Horn.
"I've been fighting at 69.85, the fight I want to fight him again to make the weight is going to be 83kg.
"I won't even make 83kg - I'll make about 78-80kg.
"He'll be probably 90kg by the time he gets into the ring.
"By the time I get into the ring I'll be 78-80kg and he'll be 10kg heavier."
Regardless, Mundine backed himself to win and drew further confidence from his ever-improving hip since his career-saving operation in England in February.
He said the chronic issue had played a big part in last November's crushing loss to American Charles Hatley.
"My range of movement is just crazy now," Mundine said.
"I've never had it in six, seven, eight years - that's how long it's been.
"It gradually got worse with osteoarthritis in the hip.
"I'm really excited and that's why I'm confident I can beat Green no matter what.
"Even if he's 10kg heavier than me, who cares?"
The clinic on Thursday was to launch Charity Bounce, a not-for-profit charity developing a community program to inspire Aboriginal, Torres Strait Islander and culturally diverse youth.
