The trash talking in the build-up to Amir Khan's US debut boiled over as Freddie Roach blasted Paulie Malignaggi over his drugs smear.
The normally placid Roach exploded yesterday when asked about Malignaggi's allegation that fighters at his Wild Card Gym may not be clean.
Malignaggi claimed Manny Pacquiao's refusal to take a blood test for his clash with Floyd Mayweather Junior, which is now back on for November 13, suggested Roach's fighters may be hiding something.
Roach usually ignores Malignaggi's fast-talking because it helps sell tomorrow's fight, but feels the loudmouthed New Yorker overstepped the mark with that dig.
An angry Roach insists that Khan and the rest of his fighters are clean and that their success is down to hard work.
"Paulie brought it up that Amir may be on something because he trains with me, well, he can go and f*** himself because my guys are clean," fumed Roach.
"It annoys me, it does. It's an insult, but more so to my fighters because my guys just work hard. They have a good work ethic. That's what their success is down to. I know that for a fact.
"I feed them, we cook for them. We know what they put into them every day. It does sadden me. We've never flunked a drugs test. The commission, they run the sport, not the fighters, and they do a good job."
WBA lightwelterweight king Khan has consistently denied any suggestion that he has used drugs and claims no one at the Wild Card Gym is on any performance-enhancing substance.
"Any time they want to do a drugs test on me, I'll put my hand up and take one to prove I've never taken anything," he said. "I'm a natural athlete - like Manny.
"When they say Manny is doing drugs, I am in the same gym as him with the same trainer and nutritionist and I can tell you that it's hard work, which has changed our body shape."
Malignaggi will regret angering Roach and the man with the plan believes he has worked out a strategy to destroy the former IBF champ at Madison Square Garden Theatre.
Roach has told Khan to stay close to the powder-puff punching Malignaggi and feels his man has the power to hand the challenger the biggest beating of his career.
Ricky Hatton is the only fighter to have beaten Malignaggi inside the distance with his 11th-round stoppage 18 months ago and Roach has tried to wind him up by saying Khan will do it in three.
"I said Amir would knock him out in three rounds to wind Paulie up because he talks so much s**t, but I really do believe he will stop him," he said.
"I want Amir to stay in the pocket and fight with him. With a puncher I probably wouldn't make that same move, but with Paulie I have the liberty of doing that.
"We have been training for Amir to stay in the pocket and fight and not get out like he would normally do.
"Paulie's a mover and we have been working on moving from side to side and having Amir's presence in front of him will be the best pressure in this fight.
"He's not going to be able to shake Amir and he'll be with him everywhere he goes."
