Cruiserweight contender Isaac Chamberlain is predicting big things in the future for former heavyweight world champion Deontay Wilder.

Wilder has been out of the ring since last October, when he was stopped in the eleventh round of his dramatic trilogy bout with Tyson Fury.

Chamberlain was hired in the past to work as a training partner with Wilder.

He expects the dangerous puncher to come back in top form.

"One million percent,'' Chamberlain told Sky Sports News. "You need characters like that in boxing, he'll be back. I remember I was facetiming him before the other fights, he was in the zone and locked in. A true test of character is how you bounce back.

"He's powerful, very powerful. I remember I sparred him when I was 19, he hit me with an uppercut, I thought I was back in London. He's a solid puncher. People always say it's his power. It's not really, it's his speed. He's very quick off the mark and he processes very quickly. People don't realize it and people only think he's wild just in general. No, he's only wild when he has you hurt. But he sticks to the basics very well, he's very, very sharp. So he's better than what people think. There's method behind the madness."

Chamberlain is preparing for his upcoming clash with Chris Billam-Smith, which takes place in Bournemouth on Saturday, July 30.

Besides Wilder, Chamberlain has sparred with other top boxers like unified heavyweight champion Oleksandr Usyk.

He believes that experience will help him greatly in the bout with Billam-Smith.

"Sometimes you have to look at yourself in the mirror and think what can I do to get better?. 'Am I just going to stay here or am I going to try and evolve and better myself? I believe that that's what I've done. I went away, I went to Miami and sparred with all the world champions and world title contenders in Miami just by myself," Chamberlain said.

''I spent Christmas there, I spent New Years there, I spent my birthday there. It was very, very tough for me but I knew something was going to come out of this. I'm putting everything into my training. 'When I fight now, all of the energy that I put into my training, I put it into the fight."
