OLEKSANDR USYK warned his heavyweight rivals Anthony Joshua and Tyson Fury that he will become ‘undisputed world champion’.
The Ukrainian – who held all four belts at cruiserweight – won his second fight in the blue ribbon division.
After outpointing Dereck Chisora, Usyk set his sights on the WBC, WBA, IBF and WBO titles held by Joshua, 31, and Fury, 32.
Asked what his future holds, he replied: “Not just world champion, the undisputed world champion.”
After Usyk, 33, moved to heavyweight, he was immediately awarded the WBO’s mandatory position, per the governing bodies rules.
The masterful 2012 Olympic gold medalist has now beaten Chazz Witherspoon, 39, and Chisora, 36, since going up a division.
But he was given an early headache against Chisora, who came out on the front foot, swinging with mean intentions.
As the underdog tired, and Usyk built into his rhythm, the southpaw began to run away with the rounds.
Despite the victory, Carl Froch has tipped AJ – who was ringside for the fight – to overpower Usyk.
Froch told Sky Sports: “Has it answered questions for me to say, ‘Usyk belongs in there with Tyson Fury, or with Anthony Joshua, or even with someone like Deontay Wilder?’ I’m not so sure it does.
“I think he would struggle. The pace and pressure from Anthony Joshua, and the combination punches.
“An even bigger, heavier, more solid, fresher heavyweight like AJ – and he lands more effective shots on the target.
“I don’t know if that’s answered the questions for me. I’m not putting him up there with the top three heavyweights in the world.”
