That’s according to Whyte himself, who insists that AJ needs to rekindle the fire within him if he wants to regain his belts.
The Body Snatcher came up short in his sole title fight five months ago at Wembley Stadium, suffering a devastating sixth-round knockout loss to the WBC heavyweight champion Tyson Fury.
And despite the lingering animosity between them, he has offered some sound words of advice to his arch rival.
Speaking to Sky Sports, he said: “It’s a massive fight, the biggest fight of his career.
“I do expect him to bounce back, he’s a British fighter like me and I only support our own, so I do hope he gets the job done.
“It’s good for me if he wins as well.
“I can understand that [rediscovering his aggressive side], because I’m of the same mindset as well. In my last fight [against Tyson Fury] I wasn’t as aggressive as I normally am, I’ve said the same thing to myself, I need to rediscover that aggression.
“I think it’s the right mindset he needs going into the fight, it’s the only way he wins the fight.”
Whyte acknowledged that Joshua has appointed Robert Garcia as his new head coach – but said that ultimately it’s all down to him at the end of the day.
He added: “I honestly don’t think that will make much of a difference. He’s the one that needs to make the decision, be dirty and be nasty.
“When we fought, we fought twice, both fights we had there was a lot of aggression between me and him in the fight, that’s the difference between fighting me and fighting Usyk, that aggression wasn’t there.
“He was sort of trying to outbox someone who has been boxing for 25/30 years.
“I believe if he revisits that aggression he had for me he does a much better job and probably beats Usyk and knocks him out this time.
“Me and him are similar in a lot of ways, we come forward and throw a lot of punches, are aggressive and enforce ourselves on our opponents, I think they’ll be trying to get him back to that.”
And while he’s coming off a loss, Whyte also revealed that he would be happy to fight the winner of Joshua’s rematch with Usyk.
He continued: “I want to fight both of them win, lose or draw. I want to fight the best fighters around.
“People want to see me fight Joshua, Usyk, Wilder, all these guys, and that’s what I want.
“We have a lot of offers on the table at the minute, I think this week and next week we should look at the offers and break them down. People are away on holiday so it needs time to sift through these things.
“There’s lots of fights there, there’s Joshua, Usyk, there’s Wilder, I’d love to fight Wilder, I’d love to have another go at Tyson Fury again.
“Joe Joyce-Joseph Parker is there, there’s Daniel Dubois, but my main focus is to get back at Anthony Joshua, I’d love to have another fight against him so let’s see.
“Hopefully he gets the job done against Usyk and I get another chance to fight him against.”
