Former two division world champion Tim Bradley is confidently backing Mexican superstar Saul "Canelo" Alvarez to come away with a solid victory over undefeated WBA super middleweight champion Callum Smith.

Smith and Canelo will battle on Saturday night, at the Alamodome in San Antonio, Texas. The contest will also have the vacant WBC title at stake.

Smith holds a significant advantage in size in comparison to Canelo.

Canelo is no stranger to facing bigger men.

In November 2019, he moved up by two weight divisions to score a knockout of the much bigger Sergey Kovalev to capture the WBO light heavyweight title.

Now Canelo aims to capture two legitimate belts at 168-pounds - and Bradley fully expects that he'll get the job done.

"At the end of the day, Smith is another legitimate world titlist, and Canelo is coming up in weight from where he's spent most of his career, and taking risks. Fights like this are the reason why guys have Alvarez No. 1 over Crawford or anybody else in the boxing world," Bradley told ESPN.

"I like Canelo as a fighter. I like his style. I think he beats Smith. I think it's going to be a technical fight. Smith is a boxer, he's tall, lanky. I think he's a little bit underexperienced at the moment. Even though he has a world title, I would just say he lacks real experience against real quality fighters.

"I think Canelo beats him in a technical battle. I don't see Smith applying the kind of pressure he'll need to beat a guy like Canelo. He's going to try to maintain distance on the outside, box and pick his spots wisely against Canelo. And I just think Canelo will make adjustments and find a way to get inside and break Smith down to the body. It'll go to the scorecards, and I think he wins by a decent margin by unanimous decision."
