Undefeated Gavin, 25, defends his WBO Intercontinental title against ex-footballer Woodhouse over 12 rounds at Liverpool's Echo Arena.
"I am going to beat him. There's no question," Gavin told BBC WM.
"He doesn't hit hard enough. He doesn't throw enough punches and his feet are a joke. Come fight night, he'll see."
Woodhouse, 31, turned to boxing in 2006 after a football career that included spells with Sheffield United and Birmingham City - the club Gavin supports.
The two were scheduled to meet last September but Woodhouse pulled out of the fight due to a hand injury.
With 15 wins from his 17 fights, Woodhouse knows he is facing the toughest test of his career to date.
"So far I'd say, yeah, fighting for the WBO Intercontinental title against undefeated former amateur world champion Frankie Gavin, it doesn't get much tougher than that," Woodhouse added.
"I'm not going to out-slick him. He's got the skills, no doubt about that, but I'm going to come forward and, if I land clean on him, I'll take him out."
