ANTHONY JOSHUA has been backed to beat Oleksandr Usyk in a rematch by David Haye, but was urged to use his 'physical attributes'.
Usyk became only the third man, behind Haye and Evander Holyfield, to win titles at cruiserweight and then heavyweight.
He brilliantly outboxed AJ over 12 rounds and was crowned as the unified world champion.
Joshua has already confirmed plans to exercise his rematch clause despite the one-sided and convincing loss.
But Haye has thrown his support over to AJ and warned a change of tactics is needed - wanting a more ruthless approach opposed to the sweet science.
He told iFL TV: "Anthony Joshua has a chance to reclaim his titles, it’s going to be a mega, mega match. A fight that I believe AJ can win.
"Looking at this fight you would say no, but he has what it takes. But he needs to change a lot of fundamental things in his game.
"Just rewatch the fight with Dereck Chisora. Chisora brought a gameplan to the table.
"He doesn’t have the physical attributes of Anthony Joshua but was able to win significantly more of the rounds in a very, very close fight.
‘So if Anthony Joshua uses his physical attributes in the fight – it’s no good looking at them in the mirror, they’ve got to be implemented in the fight.
"If they can be forced on Usyk, he can reclaim the titles.
"But if he tries to have a boxing match, or does anything remotely close to what he was doing on Saturday night, it will be the same again."
Joshua, 31, confused many ringside as he selected to try and outbox the brilliantly talented Usyk, 34, who was giving away over a stone.
And Dillian Whyte, who was beaten by AJ in 2015, called for his old rival to get back to his most brutal best.
Whyte, 33, said: "Lately he’s gone into this sort of safety-first [approach]. He’s just fighting weird, man.
"You’re a f***ing big strong guy, that’s what’s worked for you, that’s what got you to the Olympic gold medal, that’s what got you to your first world title, that’s what got you to the unified world title.
"So he should have just been f***ing having a go."
