Anthony Joshua and Joe Joyce squabble on Twitter over the heavyweight clash.

ANTHONY JOSHUA and Joe Joyce fought on Twitter, as heavyweight talk increases.

Joyce is just one of many hopefuls who will fight Joshua in the event Oleksandr Usyk leaves.

35-year-old Ukrainian soldier has bravely fought for his country in the war against Russia. He is now out of the picture.

Joyce offered to fight AJ, but his sparring partner hit back. He referred to his first round win in the amateurs.

Joshua, 32, tweeted "I boxed Joe and stopped him in one round." I would do the same today. There hasn't been any change."

A week later, Joyce, 36, a normally tight-lipped individual, replied: "And @anthonyjoshua, you having a meltdown. Where are all your belts?"

"All those endorsements and sponsorships were helpful?" You're a glass-cannon. Quit the act.

Joshua jokingly said, "It took me 5 days to think about this ..."."

Frank Warren, Joyce's promoter, has already made the unbeaten Olympian available to fight Joshua.

AJ also has Otto Wallin (30), and Luis Ortiz (42), who are more suited for replicating Usyk's style.

SunSport spoke with Wallin about Fury's fight. Wallin received 47 stitches in the hospital and it was Fury's toughest fight to date.

"If you take a look at Usyk, and you want to find someone similar to him then I'm your best choice.

"They know I am interested in the fight, and I want it."

Jay Jimenez, Ortiz's manager, said that Luis "King Kong" Ortiz would love to face Joshua.
