Usyk retained his WBA (super), IBF, WBO and IBO belts after winning his rematch with Anthony Joshua on Saturday, while Fury, who most recently retired after defeating Dillian Whyte in April, holds the WBC belt. Promoter Frank Warren said a fight with Fury is “the only fight” Usyk wants and Fury has given until September 1 to arrange it. He posted on social media: “For all those suitors out there who want to do the match I’ll give you all seven days until September 1st to come up with the money if not thank you so much it was a blast I’m retired . “All bids submitted must be submitted to my attorney in writing with proof of funding, so let the games begin.” Fury, who said he was retiring from boxing less than a fortnight ago, said in an interview with TalkSport that he would want £500m to make the Usyk fight happen. After the Ukrainian beat Joshua in Saudi Arabia at the weekend, Warren said: “The challenge will be to meet the financial expectations of both guys. It has to be much bigger than that [Usyk v Joshua II] because you have two undisputed fighters and the first time the four belts are on the line. “It’s a unique situation and what adds to it is that they’re both unbeaten, which is quite unusual.” Quick guide

Thanks for your response. If the fight were to happen, the winner would become the first undisputed heavyweight champion since Lennox Lewis in 1999-2000, just the sixth of all time and the first of the four-belt era following the rise of the WBO.
