Tyson Fury and Anthony Joshua's long-awaited bout could finally come this year and would be the "biggest heavyweight match in the world".

That was the message on Wednesday from Top Rank president Todd DuBoef, a key member of Fury's United States promotional team who wants to see the all-British clash in 2023.

Joshua faces Jermaine Franklin on Saturday night at the O2 Arena in London, though speculation continues to swirl the former could face Fury after his undisputed bout with Oleksandr Usyk fell through.

Fury's promoter Hearn added fuel to the fire after expressing hopes of reviving negotiations with the entourage of Joshua, who DuBoef suggested would deserve a headline fight if he defeats Franklin.

"I've always said that that is the fight," DuBoef told Sky Sports.

"Both of them have great brands, huge fanbases, and fortunately both of them come from the UK, so it's wonderful that your country has been able to produce these incredible prizefighters.

"That fight is always there, and, to me, is the biggest heavyweight match in the world, because of the personalities and the stories."

Both camps have pointed the finger at each other after an April 29 meeting at Wembley between Fury and Usyk failed to come to fruition.

"The frustration is for all of us," DuBoef added on that bout. "All of us are frustrated, right?

"And I think timing has been an issue with trying to make this fight happen. I'm not going to say never, but I think we all want to see this unification, and we all have hope.

"But there was a timeline that was set up, and it just got ahead of everybody and it became very tight.

"Fortunately, there's always hope and an opportunity because I think both fighters really know that this is what the sport wants, and what they want."

While holding out hopes over the mouthwatering fight between Fury and Usyk, DuBoef says his client could even face both the Ukrainian and Joshua before the end of the year.

"That's the way we move," he continued. "We move with immediacy, and we move trying to figure out and get rationality to a situation.

"I think we've always wanted this fight for Fury and Joshua, and we've wanted to see Fury and Usyk, and Tyson has wanted that, and the Warrens, and we've worked hard in getting this done.

"I would love to see, and you've just laid out a great 2023 for the Fury side, if we could do Usyk and Joshua this year, it would be fantastic."
