David Lemieux is confident he can stun boxing by taking out Gennady Golovkin when the pair meet this weekend.
The knockout specialists each go into their New York fight with a version of the world middleweight title, and the winner will walk away with the IBF and WBA belts.
Lemieux is a 7/1 outsider with Sky Bet to end Golovkin's unbeaten record, and the Kazakh was last taken the distance more than seven years ago.
But Lemieux said: "I'm ready. It's now or never. He's at his best, I'm getting to my best. We took a big step, and we're ready for it.
"Everybody understands the gravity of this fight. I think people are going to be surprised with what I bring to the table.
"I'm a big underdog, which is perfect by me. It's not a problem. I know who I am. I have a lot of confidence in myself.
"It's not about power. It's about character, toughness and determination. We're both hard punchers; everyone knows that. Let's see beyond that."
