Former world champion Tyson Fury (25-0, 18 KOs) is baffled as to why "greedy" Anthony Joshua (21-0, 20 KOs) has not accepted Deontay Wilder's $50 million offer for a heavyweight unification fight.
Wilder, who holds the WBC world title, emailed Eddie Hearn, Joshua's promoter, last week with the guaranteed offer for a bout with the WBO, WBA, IBO and IBF champion.
Hearn questioned whether the undefeated puncher has the claimed funds and said the offer would not be taken seriously before he has seen a contract - but the two sides eventually got together and there was proof presented of the funds - although the deal is still far from done because Joshua and Hearn have a lot of questions they want answered.
But Fury believes his fellow Brit is dragging his feet and has no idea why Joshua has not agreed the deal.
He told Will Kent: "It's a lot of money if it's a genuine offer, which I believe it is. Then how much do they want?
"How greedy can one man be? $50 million isn't good enough? Well, good luck to him, I hope he gets $250 million.
"I don't know what's going on. We're prize fighters. We boxed for free once upon a time. I'm sure it's not [just] about the money."
Fury will make his comeback against an unconfirmed opponent in Manchester on June 9.
Fury has been out of the ring since November of 2015, when he upset Wladimir Klitschko for the unified titles.
He eventually dropped his belts and lost his license to box, after dealing with serious issues connected to depression and substance abuse.
But now he's lost a lot of weight, he's training hard on a daily basis, and plans to make a another big run in the sport.
The 'Gypsy King' is hoping to eventually get both Wilder and Joshua in the ring in the coming future.
