Tyson Fury has stated a deadline of September 1st for the fight with the fellow heavy-weight boxer, Oleksander Usyk, for £500 million.

In a story posted on his Instagram story, the Gypsy King" stated -

"to all these suitors out there who want to make the fight, I'm gonna give you all seven days - til September 1 - to come up with the money.

If not, thank you very much it's been a blast!".

Fury announced his retirement from boxing on his 34th birthday following his decorated career and number of heavy-weight belts. Usyk, retained his WBA (super), IBF, WBO and IBO belts following his rematch with Anthony Joshua.

The boxer later added whilst on the radio show talkSPORT, Fury added - "Everyone keeps asking me about this Ukrainian guy. Are you going to fight, are you going to do this, are you going to do that?'

I've made it very clear I'm retired from boxing and I'm very happy doing that. However, I will come back but it has to be for an obscene amount of money.

Because let's face it, it's not Anthony Joshua which I would have done for free, it's some foreigner who no one really cares about, and that's it."

Fury claims he would've fought for the title of undisputed heavyweight champion for free had Anthony Joshua defeated Usyk in last weekend's Saudi showdown.

Fury continued - "If they want the big Gypsy King to fight, then they have to pay an obscene amount of money. For the biggest fight in the world, it needs to be the biggest pay packet in the world.

However, Mayweather got 400million for Pacquiao. I want 500million for Usyk. They've got the money."

Oleksander Usyk, also seems interested in the prospect of a fight himself as he revealed after defeating Anthony Joshua for the second time, that he would only fight "the best" eluding to Tyson Fury.

The boxer has stated the bid must be brought forward by September 1st otherwise he will remain in retirement.
