Johnny Nelson, the former cruiserweight champion, warned that Anthony Joshua could find himself in a "world of trouble" if he approaches his upcoming bout with Tyson Fury with the same level of performance he displayed in his most recent fight. The much‑anticipated all‑British heavyweight showdown has finally been set for December 11 at Cardiff's Principality Stadium, and the stakes could not be higher for both combatants. Joshua enters the ring still reeling from a dramatic episode in his July victory over the relatively unknown Kristian Prenga.

In that encounter the 36‑year‑old was knocked down twice in the opening round before ultimately stopping Prenga in the second. The knock‑downs raised eyebrows because they suggested a vulnerability that had not been evident in Joshua's earlier career. Adding to the drama, that fight marked Joshua's first appearance since surviving a devastating car accident in December 2025, an incident that claimed the lives of two close friends, Sina Ghami and Latif "Latz" Adodele. Nelson reminded viewers that the psychological toll of such a tragedy can be profound.

"Mentally, you have to remember that almost a year ago AJ was involved in a horrific accident. That's a lot to get over and get his head around.

Hopefully he's in a great space with that," he told Sky Sports News. Nelson was blunt about the implications of Joshua's most recent performance.

"His last fight didn't represent him very well. If you're going on his last fight, he's in a world of trouble," he said, emphasizing that the knock‑downs could be a sign that Joshua's athletic edge is beginning to fade. By contrast, Fury's recent record looks more reassuring. After two defeats at the hands of Oleksandr Usyk in 2024, the British champion has bounced back with convincing wins over Arslanbek Makhmudov and Mariusz Wach this year.

While Fury's last bout was described as "underwhelming," Nelson argued it was far less concerning than Joshua's recent display. "If you look at Tyson Fury, his last fight was underwhelming but it wasn't worrying.

So, the stages they're at, if you're going by their last fights, the one that's in a better condition I'd say would be Tyson Fury, because his last fight read better than AJ's last fight," he explained. The former cruiserweight also highlighted a fundamental difference in the way the two heavyweights win fights.

Joshua, according to Nelson, relies heavily on explosive power and athleticism. "Without a doubt, Joshua is explosive. You saw the fights when he boxed people like Francis Ngannou, took them out cold," Nelson said. Fury, on the other hand, possesses a more rounded skill set that includes technical boxing ability, ring intelligence and stamina.

"Tyson Fury, we've seen him box and knock people out. We've seen him go the distance. We've seen that slow burn and him winning a fight," Nelson noted.

"With AJ, it just seems that he stands out more for the knockouts than his boxing ability, even though he does have boxing ability. Whereas Tyson Fury, it wouldn't surprise you if he boxes his way around the ring for 12 rounds because he has that ability." Nelson went on to speculate how the fight might unfold depending on the style each fighter brings.

If Joshua seeks an early, high‑impact finish, his raw power could be decisive, but it also carries the risk of a premature stoppage if he cannot land cleanly. "Is AJ going to produce a crash, bang, wallop? Most people would probably be saying if it stops early inside the distance, you'd say AJ because of that explosive power," he said.

Conversely, if the bout drags into the later rounds, Fury's superior boxing IQ and endurance could give him the edge. "If it goes the distance or it's a late stoppage, you'd say Fury because he has the boxing intelligence, IQ and success of stopping people late," Nelson added.

Both athletes are undeniably past the physical peaks of their early careers, but Nelson believes the historic rivalry between them will compel each to deliver their best performance. "I think both fighters, not just AJ, are way past their best," he acknowledged, yet he also suggested that the unique circumstances of a December 11 clash could provide a one‑night opportunity to recapture some of their former glory.

"But I also believe that because they're fighting each other, if there's ever a time that they're going to be able to turn back time for one night only, it's December 11. That one night is when they get everything." Nelson emphasized the psychological pressure surrounding the fight, noting that a single mistake could jeopardize not only the fighters' holiday celebrations but also the long‑standing animosity that has built up over years of competition.

"They understand that one mistake ruins their Christmas, ruins their New Year, ruins this beef that they've had forever and a day," he said. Despite acknowledging that neither combatant is at the pinnacle of their abilities, Nelson remains confident that the matchup is perfectly balanced for the present day. "They're not the fighters they were, but the fighters they are today match each other perfectly, and they'll bring the best out in each other."
