Anthony Joshua has been backed to produce a "destructive" performance against Kubrat Pulev.
The heavyweight world champion puts his three belts on the line against his mandatory challenger on June 20 at the Tottenham Hotspur Stadium.
Joshua is making the first defence of his titles since he won them back from Andy Ruiz Jr in their desert rematch last December.
And having put on a technical masterclass that night, his promoter Eddie Hearn expects a more brutal performance against Pulev.
"You will see one of the best AJ performances - the shackles are off from the Ruiz Jr 2 fight in terms of being disciplined and following a game plan," Hearn told Sky Sports . "He can be more destructive in a better stand-up fight.
"The mindset is the same and has been the same since day one, with a couple of tweaks. The Ruiz Jr defeat taught him not to be influenced by outside noise. Stay focused, look after yourself, be selfish.
"He gave time to everybody but this is an unforgiving sport and you've got to look after No 1. He did that for the Ruiz Jr rematch and he will do it again.
"He's been working since the Ruiz Jr rematch. There hasn't been a week where he hasn't been in the gym working on tactics, ability and technique. He's absolutely driven to be the best.
"This isn't a guy who fights then goes on holiday to have a few pints and a couple of pizzas, taking three months off with the kids. He is working day in, day out. He's an absolute role model to any athlete and any individual in sport."
Joshua's plans for Pulev could be wrecked by the coronavirus outbreak however with sporting events across Europe falling victim to the health scare.
And Hearn admitted he will not host events behind closed doors.
"We've got quite a busy schedule coming up, so we hope that it can be contained and business as usual," he said.
"For me, boxing is unique in many ways, particularly in terms of the role that the fans play in making a fighter peak in a very important moment in their career.
"I cannot see how we can stage a fight behind closed doors with no crowd. Can you imagine Anthony Joshua walking to fight Kubrat Pulev in front of you and me and Adam Smith? It's just not going to happen. "
