It's safe to say that Anthony Joshua is a wanted man in boxing, not least by Joseph Parker.Joshua is keen to unify another belt in his next fight, with WBC champion Deontay Wilder and Parker with his WBO belt both available for discussions.AJ's promoter Eddie Hearn wants him to become the undisputed heavyweight champion by the end of 2018, which would mean beating both of those men.Earlier this week, the Watford-fighter was keen to talk up his prospects, and said that if he beats Parker and Wilder, he would rank alongside the best of all-time, such as Muhammad Ali and Mike Tyson."When I negotiate the fight, once it's done, I'll announce it. I don't like to talk about 'I'm this, I'm that' when I haven't got it. So once I have it and I'm on the journey, say the fight is a week away, I'll say: 'I'm on the verge of mentioning my name alongside the greats like Muhammad Ali and Mike Tyson'," he claimed.However, it appears that the attention may have gone to his and his team's heads somewhat, if the offer Parker claims to have received from Joshua is to be believed.The Kiwi tweeted him two days ago slamming the derogatory offer he got to make the fight, and questioned whether AJ is really interested in making it happen.

And earlier today, Parker went back for more, though this time publicly declared the fee he is after for the unified title match.

Boxing fans were taken aback by Parker's demands though, and tweeted him in no uncertain terms that he doesn't deserve the 40% he has requested.

While Joshua's name is undoubtedly more known worldwide than his potential opponent's, the Auckland-born man has every right to what he perceives to be a fair deal, with his manager David Higgins saying they will accept "not one per cent less" than 40% for the bout.

As a heavyweight champion of the world himself, to be offered "less than half" of what Charles Martin got for a vacant title fight with AJ does seem to be somewhat degrading.

Parker won the belt last December against Andy Ruiz in his hometown via a majority decision, and has defended it successfully twice, both on points, against Razvan Conaju and Hughie Fury.

However, there are arguments to suggest that the Kiwi doesn't deserve such an amount, as just 8,000 fans have seen his last two fights, whereas ten times that were at the Principality Stadium to see Joshua stop Carlos Takam in the 10th round.

AJ is unlikely to be swayed by Parker's latest tweet though, given comments he's madewhile on holiday in Dubai.

He told Gulf News that creating interest on social media isn't how professionals handle things, so it would be hard to imagine the offer being upped too much.

"When I fought [Wladimir] Klitschko, he wasn’t on social media saying ‘I want to fight Anthony’, we worked on it behind closed doors, got a deal done and then announced it to the public," he said.

"That’s how a true professional does business."
