Billy Dib will be the underdog against American Tevin Farmer when they fight for the vacant IBF junior lightweight title in Sydney on Friday.
Tough lessons learnt in life and from legendary boxer Jeff Fenech have Billy Dib believing he can maintain his pristine professional record in Australian rings and upset American Tevin Farmer in their world title fight on Friday.
Dib (43-4, 24 KOs) will fight in Sydney for the vacant IBF junior lightweight title after Japan's Kenichi Ogawa was stripped of the title for failing a drug test in his win over Farmer last December.
The result was changed to a no contest, meaning Farmer (25-4-1, 5 KOs) remains unbeaten in almost six years and 18 fights since dropping four and drawing one of his first 12 bouts.
All of Dib's professional losses were overseas and he pointed out Farmer has never fought outside the US in his time in the paid ranks.
The American is a strong betting favourite, but Dib has plenty of big fight experience to draw upon and has been steeled by adversity in and and out of the ring.
He was prepared to give up boxing after losing to the then WBC super featherweight world champion Takashi Miura in May 2015.
It was a third world title defeat in just over two years for Dib who lost his IBF featherweight crown and a rematch to Russian Evgeny Gradovich.
He also experienced tough times outside the ring with his first wife dying from cancer and a divorce from his second wife.
Dib rediscovered his passion for boxing and has changed things since teaming up with triple world champion and experienced trainer Fenech last November.
"He's tightened up my defence, he's worked on my punch output and more importantly he's worked on my mental strength," Dib told AAP.
'He's pushed me to points in training where I thought I was going to vomit.
"I'm ready and physically and mentally capable of anything.
"After everything that I've been through in life, I feel that I'm ready for anything that happens.
"Whatever Farmer comes with we're going to be ready, we've worked extremely hard.
"The life lessons I've had will get me over the line in this fight."
Fenech was impressed with the way Dib had applied himself in the short time they have worked together.
"The guy who came to me eight months ago couldn't have done a quarter of what he's doing today," Fenech told AAP.
"His punching, his fitness, he looks young, healthy and strong."
The undercard features two of Australia's brightest prospects in bantamweight Brock Jarvis and middleweight Tim Tszyu.
