Tyson Fury has stoked the fires of controversy surrounding his July rematch with Wladimir Klitschko by labelling the former world champion 'a pussy and a boring old c***'.
Klitschko travels to the Manchester Arena to fight Fury on July 9 and the 40-year-old Ukrainian is in a training camp as he prepares to try to take back the WBA, WBO and IBO heavyweight titles.
Posting on Twitter, Klitschko said: 'I arrived at camp and I'm happy to get back to work and prepare for the battle. #NowMoreThanEver.'
Unprompted, Fury responded to his rival with the message: 'u are a pussy, & a boring old c***, be ready to fall bitchko.'
It is just the latest stage of the quarrelling between the pair that will add another loud bang to the box-office promotional drum for their rematch.
