Queensland underdog Alex Leapai has likened himself to Mike Tyson and boldly declared Wladimir Klitschko's long reign at the top of world heavyweight boxing is about to end.
Leapai, the Samoan-born Logan delivery truck driver and ex-con, is preparing for the biggest pay day of his largely-unheralded career after securing a unified world title bout on April 26 in Germany.
The 34-year-old signed the contract in Brisbane on Tuesday morning after two months of negotiations were finalized overnight.
Leapai set up the showdown with Klitschko when he stunned the boxing world by defeating Russian Denis Boytsov in November to become the top WBO contender.
He has been written off in Europe and by bookmakers around the globe but Leapai and his Gatton-based trainer Noel Thornberry said the Ukrainian great's 61-3 (51 KOs) record - seeing him dominate the division for a decade - counted for naught.
Leapai claimed Klitschko had bolstered his record with a string of soft opponents in recent years.
"I don't believe this guy has faced anybody with the power that I've got," said Leapai, who has a 30-4-3 (24 KOs) record.
"It ain't going the distance. I promise you one of us is going to be knocked out, but it isn't going to be me."
Klitschko - defending the WBA, IBF, WBO and IBO belts against Leapai - holds a 15cm height advantage but the Queensland isn't daunted ahead of one of the biggest fights in Australian boxing history.
"Tyson was only a short fighter and he dominated for so many years. He had the power and I've got the power too," said Leapai, who turned his life around after being jailed for assault.
"It would be a dream come true. It's all about reaching that, and proving to the kids out there that anything is possible."
Thornberry said Leapai would continue his preparations in Queensland and only travel to Germany a week before the bout in Oberhausen.Tags: Wladimir Klitschko , Alex Leapai , Klitschko-Leapai , Klitschko vs. Leapai
