Former cruiserweight champion Tony Bellew has urged Anthony Joshua to rediscover the aggression that he showed several years ago, as the British star will aim to get revenge in a 2022 rematch with Oleksandr Usyk.
Last month, Joshua was outboxed over twelve rounds by Usyk, who walked away with the IBF, IBO, WBA, WBO world titles.
Joshua has since exercised an immediate rematch clause, with the second bout being targeted for March.
During the recent encounter, Joshua was rarely using his size advantage and tried to outbox a fighter with superior skills.
Many observers believe Joshua has not been the same fighter since suffering a knockout loss at the hands of Andy Ruiz in June of 2019. Joshua outboxed Ruiz in their rematch six months later.
"I think there are certain things that need igniting in Anthony Joshua. Maybe the aggression, maybe back to what he was doing before the Dillian Whyte fight," Bellew told DAZN Boxing.
"That fighter is still in there, he's gotta find a way to ignite that in himself again."
Bellew is not the only boxer to provide such advice.
Former super middleweight champion Carl Froch wants to see Joshua go all-out in the second fight - with new tactics being implemented.
"Now, if you've got height and reach and weight advantage on somebody that's better than you technically, it's a no-brainer," Froch told Boxing UK.
"F------ get on him, ragdoll him, push him back, lean on him, hit him round the body, hit him low, f------ drop the nut on him if you have to. Get the win, don't sit back, poncing around, flicking the jab out and just waiting and that's what it was. Disappointing performance for AJ, one he can massively improve on, quite easily. So you can't write him off in the rematch but he needs to change his tactics."
