Curtis Woodhouse has vowed to stop Frankie Gavin when they meet on July 16 in Liverpool.
The pair clash for Gavin's WBO Intercontinental Welterweight title.
And challenger Woodhouse believes that he can expose Gavin's untested chin.
"He mocks me for 'fighting bums', but who has he fought as a pro?" Woodhouse told boxrec.com
"I've had some excellent sparring with some quality southpaws, and Gavin is in for a shock! I just can't wait to get in the ring.
"I'm under no illusions. It's not going to be easy.
"I can't outbox him or outpoint him, so I am going to have to take him out. Let's see what Gavin's chin is like once I land on it. He can't stay out of my way for twelve rounds."
