The WBO heavyweight champion puts his belt on the line against Dubois at Manchester's Co-op Live Arena this Saturday night in one of the most anticipated all-British fights of the year.

Now Wardley has questioned his opponent's approach to training after leaving Don Charles for Tony Sims only to perform a U-turn just five months later.

“It does seem very chaotic,” Wardley said of the situation during a media roundtable in London.

“It seems unsettled and doesn’t seem like the best course of action. It also seems to me like a lack of accountability. Because whenever there is a fight you lose or something goes wrong, you immediately blame the trainer, leave that trainer and find another one.

“Maybe it is you. Maybe you didn’t listen, didn’t train or didn’t do something. I think the default to look outward and blame someone is quite telling.”

Dubois’ decision to leave Charles came after being knocked out by Oleksandr Usyk at Wembley Stadium in July thus surrendering his IBF title to the Ukrainian great, two years following their first meeting.

Although the relationship was short-lived, Sims became the fourth trainer of Dubois' nine-year career after spells with Martin Bowers, Shane McGuigan and then Charles.

“Obviously it makes no odds to me and I couldn’t care less to be honest. One trainer, two trainers or no trainer—I couldn’t care," Wardley said.

“Daniel is good, very good but with all these different trainers, he hasn’t really changed.

“Stylistically he hasn’t changed and the way he approaches things hasn’t really changed, he might have some different little things, but there’s been no overhaul or difference at all.

“It’s not like there’s a new trainer and I’m going to get there on the night and be like, ‘wow, who is this? This is a whole new Daniel Dubois.’ It’s not going to be like that at all.

“He is who he is and fights how he fights. They will tweak little bits along the way but I don’t think a change of trainer has a massive effect on him like it does for some people.”

Wardley also believes that Dubois has been unable to truly change his ability to “capitulate” in fights.

The Londoner received criticism after he was stopped by Joe Joyce in November 2020 and then by Usyk in their first fight in August 2023 given the nature of both defeats.

He was accused of “quitting” by many in both fights because he appeared able to get up while on one knee, only to decide to stay down and not beat the referee’s count.

Dubois’ long-time promoter Frank Warren says the fighter put all of that noise behind him with his victories over Jarrell Miller, Filip Hrgovic and Anthony Joshua but Wardley says it is a habit that has not gone away.

He said: “It’s not necessarily something new. We knew that before from the Joe Joyce fight. Even if it never happened in the Usyk fight and it only happened once in the Joyce fight, I would still know it is there. I would still know it is in him to capitulate and back out. So, it is just more evidence on top of something I already saw there. 

“That is the contrast between us; If it is not going his way, he nose dives and if it is not going my way, I stay the course, stay focused on track and I think that is evidence of the difference in our mentality.”
