Conor McGregor has doubled down on his $100 million demand for a boxing match against Floyd Mayweather Jr.

The two-weight UFC champion repeated his demands inside a New York City nightclub Tuesday, according to a video published by TMZ Sports. McGregor is coming off a historic knockout of Eddie Alvarez at UFC 205 on Saturday.

"Much respect to Floyd," McGregor says in the video. "He's a solid businessman. What he's been able to do -- he's a f---ing animal at what he's been able to do.

"[But] as far as real fighting -- true, pure unarmed combat -- Floyd don't want none of this. Give Floyd a shout; tell him I'm coming. Tell him to run around Showtime offices. I want $100 million to fight him under boxing rules because he's afraid of a real fight."

The words were nearly identical to comments made by McGregor in August, when he fielded questions about a potential Mayweather fight during a news conference in Las Vegas.

"He's running around the Showtime offices, begging those executives to come up with the $100 million cash he needs to fight me," McGregor said then. "As soon as he gets my money, we can fight."

Mayweather, answering a question posed by USA Today about whether he was warming to the possibility of a rematch with Manny Pacquiao, reiterated he isn't interested in coming out of retirement.

"A lot of fighters in the sport of boxing may want to retire, but they have to fight because they have to," Mayweather said Wednesday. "I don't have to fight.

"I just made $300 million for fighting Pacquiao. I'm OK. Like I said before, I'm happy with my position. Once again, the money don't make me; I make money. I'm well-off. I make smart moves, and like I said before, I'm happy with where my career has went."

McGregor (21-3) made a disclosed purse of $3 million for a nontitle welterweight bout against Nate Diaz at UFC 202 in August. It is the richest disclosed purse in mixed martial arts history. The New York State Athletic Commission has not disclosed his purse for UFC 205.

Those figures do not include any additional bonuses McGregor nets, particularly from pay-per-view. Before UFC 205, McGregor estimated his total profits in 2016 would be around $40 million.

In a TMZ video earlier this week, Mayweather said he considers any comparisons made between him and McGregor "total disrespect."

Oddsmaker Jeff Sherman of the Westgate Las Vegas SuperBook tweeted that Mayweather would be a minus-2,500 favorite over McGregor in a boxing match. In comparison, Mayweather was around minus-3,000 vs. Andre Berto in his most recent fight. McGregor was around a minus-140 favorite against Alvarez.
