Andre Ward's trainer Virgil Hunter believes the light heavyweight king could survive a jump to the top weight class and "outbox" Anthony Joshua.
Ward retained his WBA, IBF and WBO light heavyweight titles on Saturday by cementing his status and the best pound-for-pound fighter on the planet with a controversial eighth-round stoppage of Sergey Kovalev in their rematch in Las Vegas.
The American, who appeared to get away with several low blows during the defeat of Kovalev, suggested he could make the jump to heavyweight in the aftermath of his victory.
And Hunter is confident Ward's ability could negate the size advantage of Joshua, who remains undefeated after beating Wladmir Klitschko and holds the WBA, IBF and IBO heavyweight belts, in a potential bout between the two.
"Fighting a bigger man, it doesn't have to do with size - it has to do with his attributes and their attributes," he said.
"If you were to single out one thing that would make it a competitive fight for yourself, you take that chance - because that's what he's here for.
"I'd like to see him fight Anthony Joshua. I'm not playing, I'm serious. I think would be a very interesting fight. I know you've got a lot of people who say 'oh, that's suicide.'
"But there are some things about Anthony Joshua that I see, that makes me think he can outbox Anthony Joshua.
"I see him outboxing Anthony Joshua, there are some things about Joshua that I see. He's a good kid, I know him, but I just see things with him in particular. And he's the best, but styles make fights.
"It would be a waste of time to go to cruiser. Just leapfrog it and go for it all."
