British heavyweight contender David Allen has vowed to test the heart of Olympic gold medal winner Tony Yoka (4-0, 3 KOs).

In the 2016 Olympic games in Rio, Yoka defeated another hot heavyweight prospect, Joe Joyce, to claim the gold medal at super heavyweight.

This coming Saturday night in France, Allen will step in the ring with the very talented prospect.

Allen is very motivated for the contest and received advise from former IBO, IBF, WBA, WBO heavyweight champion Tyson Fury.

Allen (13-3-2, 10 KOs) has far more pro experience, with bouts against Dillian Whyte, Jason Gavern and Luis Ortiz. The Cuban banger is the only man to stop Allen inside the distance. Yoka has never gone beyond six rounds.

The British boxer is not intimidated by Yoka or impressed with his credentials.

"Tony Yoka is supposed to be a big name in France, well I had never heard of him, so how big a name is he really? He's a good amateur, a good three-round fighter. This is a 10-round fight. Can he do what he does for three for 10? I don't know. If he can, he will beat me," Allen said to Sky Sports.

"I'm going to go in there, I'm going to out-think, out-box, outmanoeuvre the Olympic gold medallist. People will start to take me seriously. We get him into the second half of the fight, we get him tired, frustrated, fatigued, then I'll use my physical strength, my heavy hands," said the Doncaster man. We'll work the body, the head. We hit him everywhere we can hit him until the referee tells me to stop.

"Then we'll see if he's got the grit, if he's got the heart for the game, because he'll need it when we get past halfway, one million percent. I won't be stopping, I won't be quitting, and I'll be talking to him in English and French."
