Joseph Parker is a "dreamer" who doesn't deserve 40 per cent of a purse with Anthony Joshua and lacks the ability to compete with the British heavyweight.
That's the view of fellow Brit Tony Bellew who has delivered a personal column where he dishes out his harsh realities for New Zealand's WBO heavyweight champion.
The handlers of Parker and Joshua are locked in negotiations for a unification fight.
Bellew has penned his column ahead of his juicy rematch with David Haye in London next month.
Bellew noted the injury rumours around Haye and said he would be happy to switch his attention to Parker if the Haye fight fell over.
There have always been suggestions that Parker could fight the winner of Bellew versus Haye as another way of increasing his British profile.
Bellew, never short of an opinion, issued some warnings to Parker that weren't just limited to facing Joshua. He also suggested alternate plans for fights with Russian Alexander Povetkin and Australian Lucas Browne were worrying for the Kiwi.
"Parker is dreaming if he thinks he can take 40 per cent of an Anthony Joshua fight at Wembley. That's absolutely ridiculous," Bellew wrote in Metro as the battle over the money equation bogs down the unification process.
"A fight with Joshua is probably five times more than Parker has ever earned. He's not entitled to that. The best fight on his record is Carlos Takam and that was a narrow victory. Joshua won every single round against Takam in Cardiff. Parker's team are dining out on this WBO title and they should be very, very careful what they wish for.
"There's several heavyweights out there that can beat Parker. I'm one of them. If I was Parker I wouldn't even think of going to Russia to fight Alexander Povetkin, he would lose that fight. And then he'll be kicking himself for turning down a record payday fight with Joshua."
Bellew, who is a team mate of Joshua in promoter Eddie Hearn's stable of fighters, felt Parker was a "man of the moment" and needed to be clever with his options.
"Parker is in a great position and is champion in a time when boxing is booming again. The Deontay Wilder fight, I think, will take some time to make for Joshua. So I think it's the Parker fight that will be Joshua's next big test. And if Joshua gets to Parker before me, the New Zealander's reign will end. There's no way Parker can compete with Joshua.
"I won't tell lies, I like the fight with Parker, for myself. Parts of my team feel the same and then others don't. But, I want to look at it.
"I believe 100 per cent I would beat Joseph Parker. And I'm not talking about running from him and outboxing him like Hughie Fury did in Manchester.
"Fury showed that Parker can easily be outboxed and hit clean, but he couldn't put it all together against Parker.
"If Parker doesn't walk forward all night, there's no fight there. He walks forward and makes a fight of it all night long, but you can't expect a fighter to walk into your big hits.
"Unless you're the likes of Floyd Mayweather …
"Parker was landing on Fury, not much, but enough to win the fight. Fury will be frustrated because if he had thrown more leather, he could have won that fight."
Bellew felt Parker was the most vulnerable of the top heavyweights and that made him in demand as an opponent.
"Parker is the name out there that everyone wants. Not that he isn't good at what he does, I'm not underestimating him or trying to trash him. But, his size stops him from matching up with Joshua and Wilder," Bellew wrote in Metro.
"I do think he beats most of the other heavyweights in the world. His work-rate, chin and tenacity gets him past every other heavyweight, bar me – and maybe David Haye. I actually think Haye's power and speed would see him stop Parker. For all I say about Haye, he is a very, very good fighter."
Bellew offered a word of warning to the Parker camp as they line up a potentially lucrative trans-Tasman clash with Browne if the plans to fight Joshua fell over.
"If I was Parker, I wouldn't even touch Lucas Browne. He's a steroid cheat, forget him. Browne and Luis Ortiz should be banned for life, otherwise someone is going to be killed in the ring by a steroid user," Bellew wrote.
"That will happen one day and then we'll see drug cheats banned for life. It's sad, but that's where we are heading."
