The pair have been unsuccessful at making one of the biggest bouts in British boxing history but the promoter insists that there remains a "tremendous interest" in the fight, which could take place after Joshua's proposed bout with YouTube star Jake Paul.

Warren told Sky Sports News: "There have been a lot of talks for a long time and it hotted up again recently. It's all about whether this fight happens with AJ - for example if he fights Jake Paul and comes through it - and if Tyson has a fight. Who knows if they'll get it on.

"It's a fight that has not happened and should have happened. Is it too late? I think there's tremendous interest in the fight.

"Every time we talk about Tyson and AJ that subject comes up - when are they going to get in the ring together?

"Providing Tyson wants to carry on, I can see that fight happening. It's up to the two fighters to make it happen. If they both want it and the terms are right it will definitely happen, but nobody will force them into it."

Joshua has also been linked to a fight against former Olympic champion Tony Yoka but Warren believes that the former world champion would prefer a money-spinning contest against Paul.

The Queensberry boss said: "There is talk of both of those fights.

"I think the fight taking priority in his (Joshua's) mind - I don't look after him, I look after Tony Yoka, he just signed with us and we'd like that fight - I think the preference for AJ is to fight Jake Paul because it's a huge, huge money fight. It's a crossover fight between - well, we say YouTube - he's a professional boxer now.

"It's a big step up for Jake Paul, and that seems to be the direction it's going in. As to what he should do, he's the guy getting in the ring and taking the punches, it's got to be his choice."
