The two-time world heavyweight champion opted to head back to Davison’s “Performance Center” in Harlow, Essex during the summer.

Joshua has since confirmed that Davison will train him for the December 11 superfight with Tyson Fury and will be in his corner on the night at Principality Stadium, Cardiff on the night.

Now Wardley, who has himself been preparing for Saturday’s world title rematch against WBO champion Daniel Dubois, has suggested that the presence of Joshua (30-4, 27 KOs) has given the whole place a lift.

“[Joshua's] been back in the gym,” Wardley said. “He’s been back for a good while. It’s good to see him in the gym, he has a different energy, a different aura around him once he appears, and that gives the gym a little buzz and a different feel to it.

“He’s straight back in the mix and he’s shoulder to shoulder with the boys and normal like you’d expect.”

Joshua initially joined Davison in late 2023 and the pair enjoyed immediate success. The Watford man dismantled Otto Wallin inside five rounds that December before an even more explosive victory over Francis Ngannou, who lasted less than six minutes, just three months later.

However the pair split after Joshua was knocked out by Dubois at Wembley Stadium in September 2024 with the London 2012 Olympic champion opting to join Oleksandr Usyk’s training team in Valencia, Spain instead.

That alliance would result in wins against Jake Paul and Kristian Prenga but Joshua and Davison maintained contact throughout. Now, ahead of the biggest fight in British boxing history, "AJ" has decided to head back full time.

On Joshua’s return, Wardley said: “My belief would be that, as a fighter, you know what works and what doesn’t work for you and he, especially Joshua, is someone who’s bounced around quite a bit between trainers.

“He’s been bouncing around from trainer to trainer to trainer to trainer, and then has left one, went somewhere else, and gone, ‘Actually I know where I felt best in myself and where I got the most out of it.' That’s enough evidence and enough credit, that AJ who’s at the absolute top, the absolute pinnacle of the sport, to have left, thought ‘The grass isn’t actually greener,’ and come back.”

Davison has come under increased scrutiny over the past five months as a result of Wardley’s initial defeat to Dubois and then Moses Itauma’s shock loss to Filip Hrgovic in August.

Many thought Davison, who trains Wardley alongside his original coach Rob Hodgins, should have pulled Wardley out well before Howard Foster stopped the fight in the 11th. Then Davison was criticized after Itauma failed to beat Hrgovic despite bossing the first eight rounds of their fight.

“The whole conversation around Ben has always been incredibly frustrating,” Wardley says. “It’s so strange, because the levels at which you guys may say he’s ‘failed,' or ‘not achieved,' or not done the right job have been at the absolute pinnacle of the sport.

“They’ve been with me, fighting for a world heavyweight title. They’ve been with Moses, fighting for a world heavyweight title, with AJ fighting for a world heavyweight title. These are the top one per cent guys and it’s going be tough at the top, it’s going to be hard. You might lose, you might win.

“The game’s the game. But the level of criticism to get for that is incredible in contrast to the actual achievement of what he did.”
