British champion Anthony Joshua has slammed Joseph Parker's "negotiation tactics", claiming the Kiwi fighter is trying to "demonise" his reputation in order to secure a heavyweight unification bout.
Negotiations for a blockbuster fight have been ongoing for weeks, with Parker's camp launching an aggressive public campaign to lure Joshua into the ring.
During a news conference last month, Parker offered money for footage of the Briton being knocked down during sparring.
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 purse share.
Joshua, 28, told the BBC the 25-year-old was "trying to mislead the public's opinion".
