Former super middleweight champion Callum Smith will continue his march for a second divisional title when he returns to the ring on Saturday night, in a final light heavyweight eliminator against Mathieu Bauderlique.

Their fight is part of the undercard to the heavyweight rematch between Anthony Joshua and Oleksandr Usyk, which takes place in Saudi Arabia.

Smith believes that he's a better fighter now than when he held the WBA world title at 168-pounds.

The Liverpool boxer is now being trained by former world champion and veteran coach Buddy McGirt.

"Losing kind of highlights areas you feel you need to improve on yourself," Smith told Sky Sports News. "When you're winning, it's so easy to brush them away and you're in a good place because you're winning and you're world champion. The loss kind of highlighted certain areas and I made changes to my team and moved over to LA for most of my camp. I certainly believe I'm a better fighter than when I was world champion, and I'm confident I can be another one.

"It's just about being smart and that's what I've been working on; when to throw, when not to throw, when to move and certain positions in the ring. I'm always trying to evolve as a fighter and I think too many people get camp mixed up with 'let's get fit and in shape' rather than to improve as a fighter as well."

Smith made his light heavyweight debut last September, on the undercard of the first Joshua-Usyk clash.

He made a statement with a brutal one-punch knockout of Lenin Castillo, who had never been stopped in his career.

"That got people talking more about I announced myself in the division, I can carry my power up a division, I can punch hard at the weight, and I am improving under my new trainer [Buddy McGirt]," Smith said.

"I believe I ticked every box and I got people speaking about me. The aim now is just to build on that and keep moving forwards."
