On Thursday, former two division world champion Paulie Malignaggi lashed out at UFC champion Conor McGregor, who created worldwide headlines on Wednesday when it was revealed that the MMA superstar had obtained a boxing license in the state of California. McGregor also made an unsuccessful attempt to obtain a license to box in Nevada.

McGregor has been pushing for a boxing match with former five division world champion Floyd Mayweather Jr., who retired from the sport in September 2015.

Malignaggi spoke with BoxingScene.com and said that he was very confident of embarrassing and outclassing McGregor in a straight boxing match.

"I already said that Conor McGregor can't even beat Peter Cards in a boxing match. People actually assume that he can box. He can't box. He's got a little bit of karate, he's got some skills and he adapts in the cage very well I give him credit - but he's not a boxer, he can't box. What's funny is you have enough people who will buy into this bullsh*t [that McGregor can box], so it's up to me to really save people's time from being wasted in the Mayweather fight," Malignaggi told BoxingScene.com.

"You are wasting your time making a fight between him and Mayweather. I will do everyone a favor and kick this guy's ass so bad that he'll never even look at another pair of boxing gloves again without getting nightmares. He'll know where his place should be. I know that my place should not be in the cage and he should know that his place should be in the ring."

"Conor McGregor has become so big that people are actually in denial about the fact that he can't box. We will make this fight and there will be people who actually think that he can beat me - which is a joke, it's comical. He's going to make me look like I'm 25-years-old. He's going to make me look like I'm in my prime when I'm past my prime - that's what's comical to me."

On Friday, McGregor held a question and answer session in Belfast, and an audience member asked him to respond to Malignaggi's challenge.

"Who the f*** is that guy? I don't know who the f*** that is. I don't know who the f*** that is, but I'll slap the nose off of him if he ever mentions my name again," McGregor said.
