Eddie Hearn believes Anthony Joshua is yet to reach his full potential despite holding three heavyweight titles.
Joshua who turned 29 on Monday has a 22-0 record in the heavyweight division.
The promoter says although Joshua closing in on the “ultimate goal” of becoming the undisputed heavyweight world champion, he is still learning.
In an interview with Sky Sports, the Matchroom Sports managing director said:
“You have to say with the amount of fights Joshua’s had, he’s been absolutely faultless. We couldn’t have asked for a better progression.
“We jumped into the world title scene a lot quicker than anticipated, after 16 fights. One of the toughest things in his career so far is having to learn on the job at that level, particular against Wladimir Klitschko, Joseph Parker and Povetkin.
“He’s three or four fights away from being in his prime. Right now, he is probably a year or two away from his peak in the sport.
“People don’t necessarily realise that he’s putting himself out there in front of 80/90,000 people, fighting the best heavyweights out there while he is learning.”
Joshua holds three of the four heavyweight titles with the WBC held by Deontay Wilder the only missing belt. Hearn is confident that ‘AJ’ will soon achieve his “ultimate goal” of becoming the undisputed world champion.
“What I want his legacy to be, which is something he shares, is to be one of the greatest heavyweights of all time, to be the undisputed champion is the ultimate goal, it might happen as soon as April 13.
“We are starting the conversations now, I don’t want to wait and start from scratch on December 1 as then we’d be under pressure, I want to get a feel now and see what deal Wilder’s team may accept and then we can get somewhere close.
“It’s amazing to see this young man [Joshua] go from his O2 debut as a young kid out of the Oympics, to where he is now, the biggest figurehead in the sport of boxing, a trailblazer and the biggest idol, icon and ambassador in the sport. I’m very proud of him.
“When you live the lifestyle he leads and have the hunger and passion that he does, he’s not going to want to give it up.
“He wants to fight the very best and there’s not many more to go through, Wilder is the focus and that could be one, two, three or even four fights, who knows. Dillian Whyte, Luis Ortiz and those guys are all big fights for AJ.
“If I had to put a time span on it, I’d say he’d fight on for another five to six years, having 10 or 12 fights, it’s just important he stays healthy and keep doing what he is doing.”
