Anthony Joshua has accused Joseph Parker and his promoter Duco of "acting" and warned his rival he has already begun preparations for their expected heavyweight unification title fight.
The IBF and WBA champion hopes terms will soon be agreed with WBO title-holder Parker for a fight, potentially at London's O2 Arena, early next year so that he can begin his training camp in the first week of January.
Joshua, 28, wants to fight three times in 2018 and most recently has seen the unorthodox video made by Parker and his promoter David Higgins in which he is goaded for supposedly having a "glass jaw".
Though he has been on holiday in Dubai he has already analysed his most recent performance, last month's stoppage defeat of Carlos Takam, and is confident of applying what he has learnt if the "talking" stops.
"It seems like everyone's doing the talking for some people at the minute, so we're just trying to go direct to the source," Joshua said.
