Anthony Joshua promises to “break” Daniel Dubois for the heavyweight title at Wembley.

Anthony Joshua has vowed to “break” Daniel Dubois with his fighting spirit on Saturday when they fight for the heavyweight world championship in London.

96,000 fans are expected at Wembley, which would be a post-war record for a boxing event in the United Kingdom.

Joshua is aiming to become a three-time heavyweight world champion, while Dubois will try to retain the IBF belt he was awarded after Oleksandr Usyk vacated it in June.

When asked how he will win the fight, Joshua said: “It can happen in a number of ways. I don't rely on punching power; it takes a lot more to be a great fighter. I will beat him with my mind.”

“I gave Daniel and his entire team the respect they deserve during my training camp and that will stand me in good stead. I'm tough and so is he. May the best man win. Good luck to him and his team.”

“When I started boxing, I wanted to revive the heavyweight division in the UK, so congratulations to everyone here,” Joshua continued. “What a blessing to be back… we're ready to go.”

“I'm in top shape physically and mentally. I've also been watching some of the old fights to remind myself of what I'm capable of.”

Both men come into the fight in good form, with Dubois coming off a loss to Usyk with two dogged wins over Jarrell Miller and Filip Hrgovic, while Joshua is on a streak of three knockouts over Robert Helenius, Otto Wallin and Francis Ngannou.

Their recent records and physical attributes have led many to believe that the fight will not go the full 12 rounds one way or another. Dubois goes into the fight as the reigning IBF champion but said he wants to beat Joshua to put his stamp on the belt.

“I have to keep it and hold on to it. I have to legitimize myself by winning this fight,” Dubois said. “It's a story of a resurrection of my career. I just want to challenge the biggest, make a name for myself and make history.”

While fighting in huge stadiums is second nature to Joshua, the experience of fighting in front of over 90,000 spectators will be something new for Dubois.

Last year he fought Usyk in front of around 40,000 fans in Poland, but a Wembley crowd expected to be at full tilt will be a very different prospect. Dubois dismissed any suggestions that the occasion and facing such a crowd would be too much for him.

“I've done it many times before, but this time on the biggest stage, so the energy will be higher,” Dubois added.
