Robin Krasniqi expects to profit from what he views as Nathan Cleverly's complacency ahead of their WBO light-heavyweight title clash.
Cleverly, who will be defending his belt for the fifth time, has spoken at length of his determination to meet IBF champion Bernard Hopkins in a unification fight.
Germany-based Kosovan Krasniqi, who has lost two of his 41 contests, believes the unbeaten Welshman is in for a shock at Wembley Arena on Saturday night.
"His talk about Hopkins is showing me that he underestimates me. There must be a reason Cleverly has postponed our fight before," the 26-year-old said.
"A real professional talks about the next fight and not something that will happen in the future.
"I can sense that he is not properly prepared for me and he will see that it's foolish to talk about someone else."
Mandatory challenger Krasniqi has dubbed Cleverly the 'Princess of Boxing' in response to previous postponements of their showdown.
At yesterday's head to head press conference in London, Krasniqi gave Cleverly a skirt emblazoned with his new title before it was hurled back at him by Dereck Chisora, who fights on the undercard.
"We did some research in the news about why the fights were postponed and it was 'stomach ache', 'stomach bug', 'stomach upset'," Krasniqi said.
"So here is a skirt for you Nathan Cleverly, the Princess of Boxing."
Cleverly refused to be drawn into any mind games, instead promising to make Krasniqi his 26th victim and take a step closer to securing a clash with Hopkins.
"It was a bit of bravado and he was trying to get under my skin, but I didn't fall into his trap....I just kept smiling," Cleverly said.
"It's welcome in boxing that kind of thing, we all like a bit of fun. I'll make him pay for it on fight night."
