Having said that Fury has maintained on Twitter just today that he is done with boxing therefore any unification or legacy cementing fight is probably never going to happen.
Fury said: "I am very happy and contented to be retired. It's been a long time coming and I am so much enjoying my retirement": SKYSPORTS

But on Tuesday he said he was planning for "something big" to happen.
"We've exciting news coming," he said.
Asked in an interview with Queensberry Promotions
if he would be seen in the ring again at some point in the future, Fury added: "100%. Just like in the movie when Jerry Maguire shouted 'Show Me The Money!'."
Fury's promoter Frank Warren said he had recently been in discussions with the British boxer about a return to fighting.
While Fury says a fight against Usyk or Joshua is not in his immediate plans, he has not ruled it out at a future date.
Fury is unbeaten in 33 bouts and retirement would mean he would miss out on an opportunity to fight for the undisputed crown, and with it a chance to cement his status as Britain's greatest ever heavyweight.
Usyk currently holds the other four world heavyweight belts and he is set to defend those titles against Joshua at some point this year.
Once that fight is done, Fury suggested a bout against the winner could be possible but that it would take a lot of money to tempt him to take it on.
"What I would say to the people who want this fight to happen is: you better have a big cheque book," he said.
"Because to bring the big GK out of retirement to redeem this country - yet again - it's going to cost.
"I am a prize fighter and I do fight for prizes, but it is going to cost if you want me to do a mission on this middleweight and show what a real heavyweight does to them.
"And that will be expensive, they will need deep pockets and then we can talk."
It seems there's something brewing in the Fury camp given what he's been saying the past couple of days and he's been doing a lot of media. His next fight might only be an exhibition but as I said before, this retirement talk is almost certainly just part of Fury's game plan to squeeze as much possible money out of his next fight. He's "retired", but not if someone offers him half a billion which is pretty much what he said recently. Of course getting that sort of money almost certainly won't happen but I'm sure he's willing to negotiate. Start high and see what the best offers are. I think it's safe to assume that we will likely see Tyson fighting again. There's going to be far too much money on the line for a unification fight for all the belts. Probably not anywhere near 500k but he will end up with at least 100k minimum, maybe even double that if he wins. I don't think either Usyk or AJ will trouble him too much either so I think it will be a silly move to walk away from all the belts especially when there's not much risk on the line and that fight will be by far his biggest payday.
