Tony Bellew (30-2-1, 20 KOs) is not intimidated by his role as a massive underdog, when he challenges IBF, WBA, WBC, WBO cruiserweight world champion Oleksandr Usyk (15-0, 11 KOs).
The fight is set for November 10 at the Manchester Arena in Manchester.
In July, Usyk unified the entire division when he dominated unbeaten Murat Gassiev over twelve rounds to win the first World Boxing Super Series cruiserweight tournament.
Bellew was a huge underdog when he moved up to heavyweight, and scored back to back knockout wins over two-division world champion David Haye.
Now he returns to cruiserweight, hoping to end his career by capturing the unified crown.
"The only thing I can say is - out of all the opponents he's faced, I am the only one who when he looks into my eyes, I will not be in awe of him. I have no fear of him," Bellew told Sky Sports.
"I have 100 percent belief that I'm going to take him apart. Out of all the guys he's faced, none of the other guys believed that. They just don't believe it, and I'm crazy enough to believe it."
Bellew has seen some flaws in Usyk game, flaws that have provide the Liverpool boxer with some added confidence.
He also feels the Olympic gold medal winner has never been tested in a true drag-out contest.
"I have more knockouts than Oleksandr Usyk has fights," said Bellew. "While Oleksandr Usyk is a former amateur world champion, a former Olympic gold medallist, a current world champion, a current undisputed world champion, there are still some things that he hasn't experienced in the professional ranks.
"There are some things that he's going to experience in the first round when he faces me. We'll just see how it plays out. Has Oleksandr Usyk ever had to get up from a knockdown? Has Oleksandr Usyk ever had to come through a horrendous cut?
"He has had to come back from being behind on points, to be fair, because I had him behind in the [Mairis] Briedis fight. He was down four-two on the cards after six rounds against Mairis Briedis, but he found a way back, and mainly because Mairis Briedis took his foot off the gas, and tired rapidly. But there's a reason why he tired rapidly. These guys don't look at the fight game and the boxing world in the same way as I do."
