Veteran trainer Virgil Hunter, who guided Andre Ward to unified title runs at super middleweight and light heavyweight, does not see a single fighter in either division that has a concrete shot of beating Mexican superstar Saul 'Canelo' Alvarez.

Among the boxers in his stable, Hunter trains rising light heavyweight contender Joshua Buatsi.

Canelo currently holds the WBC, WBO, WBO world titles at 168-pounds.

He hopes to unify the entire weight class in September with an undisputed showdown against IBF world champion Caleb Plant.

While Hunter is not sure if Plant is capable of winning, he expects him to put forth a better effort than Billy Joe Saunders did in May.

"Plant does bring some tools to the fight. Whether or not they are enough to hold Canelo off? It remains to be seen," said Hunter to Sky Sports. "Plant will put up a better fight than Saunders because he is taller and more comfortable at the weight."

If Canelo overcomes Plant, there is a realistic possibility that he'll return to the light heavyweight limit of 175-pounds.

He went up to 175 in 2019 and knocked out Sergey Kovalev for the WBO title. He would later vacate the belt and drop down to 168.

"Right now Canelo has so many options. It is difficult to find one standout guy who would beat him. I would have him competitive in any fight, even light heavyweight against Dmitry Bivol or Artur Beterbiev," Hunter said. 

"Beterbiev's age would give [Canelo] a chance. Bivol seems to fight at one-pace, he doesn't take it to the next level. He hasn't been busy. Canelo has an advantage to call his own shots to stay busy. Although it can back-fire - stamina-wise, in the Billy Joe Saunders fight, I felt that he started to tire before he landed that punch. Saunders' feints and antics were mentally getting to Canelo which subjected him to physical fatigue. If that punch hadn't have landed, it would have got a lot more interesting, based on his fatigue.

But there is not a fighter at super middleweight or light heavyweight that has a sure shot of beating him, but there are fighters you want him to compete with. David Benavidez, for example, is a strong guy who won't back down with hand speed, height and reach."
