Despite having only thirteen fights, Joshua has impressed sufficiently enough for most who gaze upon his ‘Greek God’- like physique and one-punch KO power to see that the sky is the limit for the current Olympic champion.
Matchroom boss Hearn, who has overseen Joshua’s entire pro career, is no different and sees Joshua possibly taking over the boxing mantle from pound for pound king Floyd Mayweather Jr, or even surpassing the American’s considerable achievements.
“We have got someone, in my opinion, who could be the biggest star in boxing since Floyd Mayweather…or even bigger,” Hearn told talkSPORT.
“I think he can transcend the sport, and not just in this country.”
Asked about when fans could expect Joshua in a world title fight and who he may face in the future, Hearn added: “He’s number two in the WBC and all the governing bodies are trying to put him up in to the mandatory position already, but he’s just not quite ready.
“It’s really the case of that he needs the rounds, and it’s trying to find people that will give him rounds. It’s very difficult, the price is going up by five, ten, twenty percent every time he gets into the ring.
“But the signs are fantastic at the moment – his speed and punch power are frightening. These are very exciting times for British boxing.
“I do like the David Haye fight at Wembley next year, that’s a great fight. I also like the Deontay Wilder fight, the Klitschko fight and the (Tyson) Fury fight.
“He’s not going to have a problem with any of them and he’s going to do huge numbers at all times,” he stated.
