Anthony Joshua's rise to the top of heavyweight boxing has been nothing short of remarkable.

From being Watford's newest boxing prospect to knocking out Wladimir Klitschko in front of 90,000 at Wembley Stadium, Joshua has asserted himself as a global name in the sport.

Following two consecutive wins over Carlos Takam and Joseph Parker in Cardiff, the 28-year-old has made the necessary steps forward in becoming the unified heavyweight champion.

Joshua currently owns the IBF, WBA, and WBO straps.

There is one fight that has been on everyone's lips since the Parker clash, however, that being the match-up between Anthony Joshua and Deontay Wilder.

Wilder currently holds the WBC heavyweight championship, and a fight between the two would crown a new unified champion.

Reports suggest that negotiations to pen a deal for the bout have been underway for quite some time now. However, the decision of where the fight will take place has seemingly halted these talks. 

Boxing promoter Frank Warren has urged Joshua to accept an $80million deal to fight Wilder in the US. 

He said: "They're saying they don't want to go to the States and Anthony is saying he owes a UK fight to his fans. I'll tell you what, Ricky Hatton's fans had the best days out in Vegas.

"You can only assume the reason it's not happening is because they're paying him $80million for his next two fights in the UK."

Wilder took to social media to publicly offer Joshua $50million to fight him across the pond, and Warren believes there are question marks from Team AJ regarding the legitimacy of the offer.

"First of all, there was a genuine offer made of a guarantee of 50 million dollars," Warren said. "Whatever happens, he's going to get 50 million.

"Then, in accordance to the rematch clause, he'd get 30 million. So, over the course of six months he could stand to make 80 million dollars, minimum. That was the deal."

UK promoter Eddie Hearn responded to the offer, concerned as to whether it was legitimate or a PR stunt.

Hearn recently signed a $1billion deal with DAZN to broadcast events in the US and UK, and Warren suggested the monster partnership is the reason behind Joshua rejecting an offer from Wilder.

Warren said: "I'd take the offer (to fight Wilder), where else is he going to get a guaranteed $80million in the next six months? But they must be guaranteeing him that, otherwise why would they turn it down? They must have guaranteed Joshua 80 million out of that billion they've got."
