Deontay Wilder retained his WBC heavyweight title earlier this month with a late stoppage of Luis Ortiz.

The American has done his part of the bargain, now Anthony Joshua needs to knockout Joseph Parker to set up, quite possibly, the biggest fight in heavyweight history.

AJ has a perfect record of 20 fights and 20 wins with 20 KOs while Wilder, four years his senior, has won all 40 of his fights with 39 of them ending in a knockout.

Joshua already holds the IBO, IBF and WBA world titles and he has the chance to add Parker's WBO strap to his resume when they meet on March 31, too.

The thought of two unbeaten, knockout specialists going head-to-head for all the belts is a tantalising prospect, but Wilder insists he hasn't negotiated for a bout with Joshua yet.

“Nothing has been offered, nothing,” Wilder said.

“Even when [Eddie] Hearn and his father [Barry] came to America last year, they weren’t talking about Joshua.

“Joshua wasn’t in their mind. They were saying ‘you guys and Dillian Whyte’. Like I said before, I would fight Dillian Whyte no problem. That’s easy.

“As long as you have Joshua on the end of that, we’re good. And they didn’t even want to make that happen.

“That was the only thing that was going. There wasn’t anything about me and Joshua discussed. Nothing. Not one thing.

“They come back and said we didn’t make an offer, we didn’t reach an agreement. How can an offer be made when the main subject wasn’t even discussed – we’re talking about Wilder vs Joshua.”

Wilder received £2.1 million for beating Ortiz even though Hearn offered him £4.5 million to face Dillian Whyte.

So what would it take to fight AJ?

“You’ve got two great guys, two undefeated guys that have knocked out everybody placed in front of them, in their prime. One from the UK, one from the USA, coming together. What a special night, what a special fight."

“I’m going to offer you 60/40 split in his [Joshua’s] favour first fight, rematch clause, winner gets it the other way around – are you accepting that?” host Adam Catterall asked.

“I’m there,” Wilder replied.
