Supremely confident former champion Anthony Mundine (44-4, 26KOs) refuses to believe he can lose his January 30 world title fight against fellow Australian Daniel Geale (28-1, 15KOs), the IBF's middleweight king.

Mundine, 37, believes a win over Geale in Sydney later this month will put him in line for big fights and big pay days. Mundine won a close split decision over Geale in 2009.

And he's certain he'll take care of Geale to open those doors.

"He can't beat me. Everything he does I do better," Mundine said.

The big-talking boxer again declared himself the best athlete Australia has ever produced in a promotional video for the bout.

"There's no one out there like me," Mundine said.

"When it comes to sport there's no one who can surpass me because no one's walked my walk, no one's done what I have done.”

Few sportspeople polarise public opinion like Mundine, and the ex-rugby league star said he thrived on his detractors.

"I need the haters, I need the haters man,” he said.

"If I didn't have my detractors and critics I wouldn't be who I am today.

"I am the best athlete ever produced in this country, ever, my name is going to live for eternity."
