David Allen insists he is not going to Paris to simply lie down for the reigning Olympic super heavyweight champion.
Allen is set to face Tony Yoka in his native France on Saturday night in an eyebrow-raising contest.
Most commentators expect Allen to suffer defeat this weekend and there have been plenty of questions over the logic of taking the fight.
The Conisbrough heavyweight says he knows full well what he has got himself into and insists he will see off Yoka.
“I know the size of the task at hand,” he told British Boxing Television.
“Beating a world and Olympic champion, it would be a massive upset.
“I’m not going over there to lose.
“I went 17 rounds with Luis Ortiz and Dillian Whyte, who are better fighters than Yoka, and I’m a better fighter after that than I was.
“I’m going over there to win – 100 per cent.”
Allen has been working towards a major fight since his Commonwealth title rematch with Lenroy Thomas in March was ended by a severe cut in the first round.
He rejected the opportunity to face rising star Daniel Dubois and opted for the Yoka clash, saying he did not feel he could turn down the opportunity.
“I’ve been waiting for a big fight,” he said.
“The Dubois fight came up and we turned that down hoping something else would could up.
“It didn’t but then the Yoka fight did. A former Olympic champion, in Paris.
“I’m not really in a position where I can turn these sort of fights down.
“We took it, we go over there, we take our chances.
“It’s a big ask but I’m confident I can get a result.”
Yoka won super heayweight gold in Rio in 2016 and turned professional last year.
Since then he has won all four of his pro fights, stopping three early.
Despite Yoka’s obvious talents, Allen believes he has seen enough to suggest he can emerge victorious.
“He’s a good fighter but if I could pick an opponent it would be a tall boxer,” Allen said.
“I think he may be a bit chinny, I don’t think he’ll like it when the going gets tough.
“I’ve got to hit him first and make it a tough night for him.
“I know how hard it is going to be to turn it into the kind of fight that will give me a chance, if that makes any sense.
“I believe I can give him a lot of trouble.”
