Tyson Fury renewed the war of words with Wladimir Klitschko by taunting the Ukrainian heavyweight during a remarkable outburst ahead of their 9 July world title rematch in Manchester.

The WBA and WBO champion will take on Klitschko for a second time eight months on from their first duel when the Briton won by a unanimous points decision in Dusseldorf.

Fury and Klitschko will face-off again after months of deliberation over a date for the rematch, which was temporarily thrown into doubt after the Manchester-born fighter claimed talks had stalled. Despite the delay in confirming the second bout, the 27-year-old has wasted little time denouncing Klitschko during another stunning press conference involving the pair where the circus surrounding the heavyweight champion swelled to an immeasurable level.

The build-up to their first fight last November was littered with jibes from Fury and their latest confrontation was not without incident. During a press conference in front of dozens of reporters and countless members of his entourage, Fury removed his shirt and claimed 40-year-old Klitschko – who had been undefeated for 11 years before losing his heavyweight crown – was defeated by a man "as fat as a pig".

"It is a disgrace to call me an athlete, you can't call me an athlete," said Fury, who has only recently returned to training ahead of his competitive return. "Absolutely not. Shame on you, shame on you. My body relieved you of all your belts and I don't take boxing seriously.

"I don't care about boxing, it is mainly about making a few quid and that's it. If that is all a professional can do then god help us all. What is the point practising for 40 years if you can't beat a fat man? Can I fight? Yes. Does it matter what a pit bull looks like? Does it f**k. Fat as a pig, 30 stone and I could beat you here and now."

Victory over Klitschko would set up the tantalising proposition of a fight with newly-crowned IBF champion Anthony Joshua – who beat Charles Martin to claim his maiden world title – or David Haye who has recently return to the sport after shoulder surgery. Fury is willing to fight either and is ready to re-write the British boxing record books.

"There hasn't been a good British fight ever in my opinion, they've all been s**t," he added. "I am the best ever out of these shores. I have to be gypsy don't I. I'm ethnic, whatever that means, I'm not English, I don't bow to no flag.

"[Father John Fury] convinced me to carry on to beat up on a few more Brits, there are a few more Brits I want to beat up on before I move to America. I mentioned no names but I am going to splatter them. I don't even know who [Anthony Joshua] is.

"I'll be like a pit bull ravishing a labrador around a playground. You can take as much drugs as you need, lift as much weight as you want; you can't put muscles on the chin. When the chips are down I'll fight until I die, you've got to knock me out. It's about beating up on bums."
