As drama continues to heighten surrounding the much-anticipated match-up between Floyd Mayweather and Conor McGregor, McGregor’s former sparring partner, who quit just last week after Conor’s team uploaded questionable photos of the Irishman working him in the ring, now continues his verbal assault.

“This guy is one of the biggest dirtbags I’ve ever met in my life – bar none,” Paulie Malignaggi insisted when speaking on The MMA Hour. “I was amazed at what a dirtbag this person is. I don’t care if we never speak again. My life is fine if I never see Conor McGregor again.”

Malignaggi, who himself is a former boxing world champion, went on to add, “I was dumbfounded by the way things were. It’s just about status with him. It makes me doubt if he ever really went through a tough time in his life like they try to say he did. If somebody went through that tough a time in life just a few years ago, they wouldn’t treat people who were not as fortunate as him that bad.”

Again, the last straw for Malignaggi was a selection of photos that appeared to show him getting knocked out by McGregor. Paulie says he was merely tripped, however.

“He doesn’t want to be put in those positions. He wants to be the front runner,” Malignaggi stated. “He wants to be the guy who always has the advantage, because when he has an advantage he’s a big man. When he gets tired, he wants out of a fight.”

And while Conor is no doubt set to make quite a pretty penny for his fight against Floyd Mayweather, Malignaggi reports that his accommodations while training were less than desirable.

“[My accommodation was] in a dilapidated neighborhood. It’s a rundown house. I mean, yeah, it works. But it’s not really what you expect. … It reminded me of some kind of crack house that had been barely renovated a little bit.”

So, might we have a Conor McGregor versus Paulie Malignaggi match-up after this Mayweather bout?
