Promoter Eddie Hearn of Matchroom believes Mexican superstar Saul "Canelo" Alvarez will target a unification fight with WBO beltholder Billy Joe Saunders in 2021.

On Saturday night at the Alamodome in San Antonio in Texas, Hearn's fighter, Callum Smith, was battered over the twelve round distance by Canelo.

The victory made Canelo a four division world champion, as he walked away with the WBC, WBA super middleweight titles.

After the fight, Canelo proclaimed that he was going to target the remaining world titles at the weight.

"I feel great at 168-pounds. I don't want to fight the scales and after 13 months you can see what I can do. This is one of the best nights I have had, one of the greatest nights. I will go for more. I want all the belts, it doesn't matter who has them," Canelo said.

Back in May, Canelo was going to face Saunders - but the event was canceled due to the coronavirus pandemic.

Hearn, who also works with Saunders, has a feeling that Canelo will go after Saunders - and then target a trilogy fight with Gennady Golovkin.

"He loves to take on the best, he's a hell of a fighter. Billy Joe Saunders and then GGG in that order. I think he's going to want to pick up the other belts in the division. I think he'll go for Billy next," Hearn told BBC Sport.

Before he starts chasing down a unification with Saunders, Canelo will first have to satisfy a WBC mandatory obligation to Avni Yildirim.

Before Canelo-Smith was finalized, Yildirim was in line for a mandatory shot at the WBC title.

The sanctioning body worked out an agreement between the involved parties - and that agreement allowed Canelo and Smith to collide for the vacant WBC belt. As part of that deal, the winner would have to make a mandatory defense against Yildirim in 90 days.
