Junior middleweight contender Tim Tszyu is motivated to replicate his father's tremendous win from 21 years ago.

In 2001, Kostya Tszyu traveled over to Las Vegas and scored a sensational stoppage of Zab Judah to become the undisputed junior welterweight world champion.

On January 28, at the Mandalay Bay in Las Vegas, Tim Tszyu will attempt to pull off a major undisputed win of his own when he challenges Jermell Charlo for the IBF, WBA, WBC, WBO junior middleweight titles. Showtime will televise.

"Man, that [fight my father had with Judah] I've watched so many times," Tszyu told AAP.

"Everyone's dad growing up is their super hero and that's the fight that made him an actual super hero not just in my eyes but to the whole world. So, yeah, that fight does bring a lot of inspiration out because it sort of cemented his name into history. I get motivation and influence from that, for sure.

"To be compared to the greatest fighter who's ever fought out of Australia is not a bad thing, is it? Doesn't bother me. I don't really care. I think I've already emerged. I've created my own character, my own start in many different ways. But this will be different. This is history. This is something else."

Tszyu (21-0, 15 KOs) is a tremendous underdog in the fight, with Charlo (35-1-1, 19 KOs) holding a clear edge in experience.

"I think Charlo's very beatable," Tszyu said. "He's a very good fighter, he's excellent at what he does but he's definitely beatable.

"I don't want to make any predictions but I'm in crazy, phenomenal shape and I'm only starting to peak now. Mentally and physically I'm in a great position and that will play a big part in what's ahead."
