Anthony Joshua has fired back in the war of words with Joseph Parker, claiming the Kiwi star is trying to "demonise" his reputation in order to secure a heavyweight unification bout.
While negotiations for a blockbuster clash have been ongoing for several weeks, Parker's camp have launched an aggressive public campaign to lure Joshua into the ring.
Last month, they released footage of Joshua, the IBF, WBA and IBO champion, being knocked down at various stages of his career and offered any 'AJ' fan $39,000 to provide video evidence of Parker being dropped.
Parker also questioned Joshua's motives this week with the Briton's promoter, Eddie Hearn, reluctant to meet the WBO champion's asking price of a 35 per cent share of the purse.
Accompanying a clip of Joshua saying that he does not box for money, Parker tweeted: "65% & rematch not enough to unify? Believe your own hype? Bubble's gonna burst bro."
But Joshua slammed their negotiation tactics and said Parker and his team were trying to mislead the public's opinion.
"I think it's not nice, I don't really respect it and I have no time for it," Joshua told the BBC.
"What's he trying? Be the big bully? Demonise everything I have done?"
"In Formula 1, golf, tennis, rugby, they are very classy people, respectable about their peers.
"Then you have people like Joseph Parker holding a press conference talking about everything he thinks I am."
Joshua confirmed his status as the biggest draw in heavyweight boxing with an 11th-round knockout of Wladimir Klitschko in front of 90,000 fans at Wembley in April.
He followed that success with a 10th-round stoppage of Carlos Takam in October to extend his record to 20-0.
The 28-year-old said he was keen to get the fight locked in but hinted that Parker was unlikely to receive a better offer.
"It would have been great to have it pencilled in now but it will happen in the future once they come to their senses," Joshua said on the BBC.
"What they are offering is nothing, and what we are offering is 10 times better than what they can bring up themselves."
