Tommy Coyle believes his professional experience will help him upset Luke Campbell in their WBC lightweight title eliminator in Hull on Saturday.
Coyle, 25, is two years younger than Campbell, 27, but has fought 12 more times as a professional.
More than 13,000 tickets have been sold for the Rumble on the Humber at Hull KR's Craven Park home.
"I'm proven in digging deep and I've experienced everything there is to experience," he told BBC Look North.
"I've been cut, I've been beat, I've been knocked down, I've made mistakes and I've lost discipline. I've pretty much done it all and Luke is yet to overcome some of those obstacles.
"I believe I'll have too much for him at this stage of his career."
Campbell, who is undefeated in 11 professional fights, turned professional in 2013 after winning Olympic gold in London in 2012.
He thinks his ability will prove to be too much for Coyle, who has lost two of his 23 professional bouts.
"I'm very consistent in my performances and they are getting better," he said.
"With my speed, strength and ability I don't see how I can't win. I'm going to go out there and do what I've got to do."
