Daniel Dubois has vowed to put Joe Joyce to sleep and march on to a world title shot.
The undefeated heavyweights will meet at The O2 in London on April 11 in a crossroads clash with the winner remaining on course for a world title challenge and the loser left to lick his wounds.
And Dubois, who has knocked out 13 of his 14 opponents thus far, vowed to add Joyce's name to his hitlist.
"I'm going to put you to sleep, bring your sleeping bag," he told his rival on Good Morning Britain. "I need this fight, I've been waiting a long time for this fight.
"This will be the fight that announces me to the world.
"I think I’m better than Joe in every department; better jab, movement, more power. The only thing Joe has over me is experience.
"This will be the most devastating performance of my career. It's a career-defining fight and after this I'll move on to a world title.
"I've got world championship potential; I'm out there to be the best fighter I can be.
"At the end of the day I'm putting Joe to sleep, come what may I'm going to be ready."
Joyce, an Olympic silver medalist in 2016, has won each of his 10 professional records but boasts the more impressive resume.
He said: "It's going to be a massive fight and he's going to get knocked out.
"All my opponents have had winning records, who has he fought?
"There’s no denying that there’s a lot on the line on both sides but experience is something you can’t buy and I’ve got tonnes of it and I believe it’ll play a huge factor in this fight.”
