Anthony Joshua has revealed he has a 'gentleman's agreement' with Tyson Fury to fight each other.
Fury, 33, made it 32-0 before announcing his retirement from boxing.
The Gypsy King knocked out Dillian Whyte in the sixth round to retain his WBC heavyweight title.
Joshua, meanwhile, is set to do battle with Oleksandr Usyk in Saudi Arabia this summer in a rematch of their title fight at Wembley Stadium in September.
Speaking to the Oxford Union on Monday, the British star admitted that Usyk is 'a tough competitor for sure'.
But he also urged Fury to look at 'the bigger picture', saying: "If Fury was in the boxing arena, was to come out of retirement and honour the gentleman's agreement, there's a lot of money to be made.
"First and foremost, I have a pound-for-pound fighter on my list in Usyk, who's a tough competitor for sure.
"People say I only focus on what's in front of me, which is a good way to be, but also I want to look at what the bigger picture holds so I can steamroll through, I have to, so I can get to the pot of gold at the end of the rainbow.
Anthony Joshua wants Tyson Fury to honour their 'gentleman's agreement'
"So, for sure, I feel like retirement doesn't mean that you've completely given up and you're on the beach clicking your phone drinking a bottle of Corona.
"I feel he's still ticking over and he'll come back if the right fight is presented to him."
However, Fury's promoter Frank Warren has insisted he will not force him out of retirement, but admits the prospect of fighting either Joshua or Usyk could change his mind.
Speaking on talkSPORT, he said: “If that happened, we’d have to work out what the percentages would be.
“I would obviously be arguing that Tyson gets more. But whatever it is settled at, that’s how it would be split.
“It would work out that there would be a certain guarantee. How these things move on is that there’s a pot and it would be determined by how much money we get into the pot with pay-per-views and things like that – then how it’s split.
“So there’s a guarantee against the split. But it could be a £200million fight. I also think the Usyk fight is a huge fight.
“The people bought into Usyk, they watched him take Joshua apart. It’s a no-brainer of a fight.
“If Tyson wants to fight, if he decides he wants to move on, if he wants to fight the winner of that fight – it won’t be difficult to make.
“I will not, in any shape or form, ask him or force him or coerce him into doing anything. It’ll be of his own free will. Boxing is a dangerous business.
"If your heart’s not in it and you’re in the ring, you’re in a dangerous place."
