World heavyweight champion Tyson Fury came out swinging on Wednesday, taking aim at challenger Wladimir Klitschko and fellow champion Anthony Joshua.
Klitschko and Fury will rematch in Manchester on July 9 for the WBA and WBO titles the Brit won in November last year.
Fury also won the IBF strap in that Dusseldorf fight, but was stripped of the title after refusing a mandatory defence.
That belt has since been won by Joshua, courtesy of a devastating second-round knockout of Charles Martin last week, with an all-British match against Fury expected to be on the horizon.
Fury was in bullish mood at a news conference to promote the Klitschko rematch on Wednesday, explaining his refusal to meet the Ukrainian in Germany again.
"He has to come and try and fight," Fury said. "He couldn't fight me first time with his A-game so he won't on his second.
"It wasn't very important for the fight to be in Manchester but it was very important that I wasn't going back to Germany.
"I wouldn't go back, end of. I wouldn't get a decision. It's in England. Wherever it was I wasn't bothered.
"I wouldn't go back because don't try and tempt fate twice. Once is good enough and I am happy with that. Let him come here. Let him come here the German p***k.
"As I am the gypsy king I don't have a hometown. Wherever I want to go is my hometown."
Fury was also quick to throw jabs in Joshua's direction, once again questioning the 26-year-old's ability and continuing a bitter war of words between the pair.
"I thought he looked like a pumped up weight lifter out of his mind on drugs," Fury added.
"The British public is thrilled by bums. You might be brainwashed by a p***y like Eddie Hearn.
"I would knock Joshua out well inside one round.
"He's had a lot to say but he wouldn't say anything around me. He's a daddy's boy and I'd give him a slap around the ear like we do to our b*****s. He's an idiot.
"What we can do to make it work financially is charge treble for the tickets and treble the price for the TV."
