LONDON, ENGLAND -- David Haye expects Anthony Joshua to accept Deontay Wilder's $50 million offer to fight for all four world heavyweight titles.

Wilder's team have made Haye's English rival Joshua (21-0, 20 KOs) a minimum offer of $50 million to meet American Wilder (40-0, 39 KOs) between September and December in boxing's first unification fight for all four major world title belts.

Haye (28-3, 26 KOs), 37, is no longer at the top table but hopes to move further up the queue if he can get revenge over English rival Tony Bellew (29-2-1, 19 KOs) in London on May 5.

The Hayemaker lost the WBA world heavyweight title in a unification fight with Ukraine's Wladimir Klitschko in 2011 and was then beaten by Bellew in the 11th round last year after suffering an Achilles injury earlier in the fight.

"If he [Wilder] can stump up $50 million I'm sure he has got a deal," Haye told reporters. "He will have to put the money in Escrow [funds held by a third party on behalf of two other parties], Eddie Hearn is not going to take his word. He's not going to be giving it him after the fight.

"He's obviously got some bigger backer. $50million for Joshua -- what does that leave Wilder?

"If they can rustle up that kind of dough, get it into a bank account and say to Joshua to fight at the MGM Grand in Las Vegas on such and such a date, and then I am sure Wilder has got a fight and Eddie Hearn can crack on.

"The deal to me sounds strange but maybe there is some mega rich oil tycoon behind it all. I for one don't know where that kind of money would come from.

"But someone seems to be chucking crazy money around. As a promoter, Eddie Hearn won't take anybody's word that the money will be there waiting for you after the fight. No, he will want cast iron guarantees."

Hearn believes the fight will get made but wants more details about the offer and says the WBC have told him Wilder is fighting fellow American Dominic Breazeale next.

Joshua, 28, holds the WBA, WBO and IBF belts after being taken to points for the first time in his professional career by New Zealand's Joseph Parker a month ago.

WBC champion Wilder, 32, stopped Cuba's Luis Ortiz in the tenth round in a seventh title defence, also last month.
