Tyson Fury has given prospective bidders for the undisputed fight with Oleksandr Usyk seven days to come up with a £500million purse.
Fury confirmed he is willing to come out of retirement to face the Ukrainian for all four heavyweight world titles after Usyk's win over Anthony Joshua last weekend. Usyk has also insisted it is the only fight he is interested in with both teams confident of reaching a deal.
Saudi Arabia is leading the race to host the fight which would crown the first undisputed heavyweight world champion since Lennox Lewis in 1999, but even the oil-rich country will struggle to meet Fury's exorbitant demands. But the Brit insists he will settle for no less than a world-record purse in a video posted to social media.
