Frank Warren thinks Anthony Joshua's promoters want to avoid a heavyweight unification fight with Tyson Fury as it would be too risky for their fighter.
Bob Arum, Fury's co-promoter along with Warren, has held preliminary talks with Matchroom Boxing boss Eddie Hearn over the prospect of a mouthwatering all-British bout.
WBC champion Fury faces a third fight with Deontay Wilder next, while Joshua is due to step into the ring with Kubrat Pulev after their bout - scheduled for June - was called off amid the coronavirus pandemic.
Warren believes the main issue getting in the way of a deal being agreed for Fury and Joshua to fight is Matchroom promoters do not want it to happen.
He told talkSPORT: "My concern, first and foremost, although they talk about it a lot, Matchroom, I don't think they want the fight. I don't think they want to put AJ in with Tyson, I really don't think so.
"I hear all the noises, but actions speak louder than words and at the moment it seems to me – and I'm not normally wrong on things like this – I've got a gut feeling they don't want it and I think that's for a reason.
"I think Tyson's the best heavyweight on the planet, there's no doubt about that, and it's a big risk for them. It's a feeling from me, I’ve never had any conversations [with Matchroom] because I don't deal with them.
"I know they've had talks with the MTK people [Fury's managers], I know there's also been conversations with Bob Arum, but I've told them all the way through this I don't think they want it.
"If Tyson, which I believe he will do, beats AJ, then they've got a problem."
Warren also revealed that an offer has been received for Fury to fight Wilder in the Far East, but refused to confirm Macau in China was the location.
"I can't say that [the offer is from Macau] at the moment, [but] it is from the Far East," he said.
"The fight will be back end of the year. All of the big fights are gonna be back end of the year."
