Mixed Martial Arts (MMA) sensation Conor McGregor has once again reiterated that he is open to face Floyd Mayweather Jr. in a boxing match in the near future.

The Irishman is fresh from his UFC 205 success in which he just took a round and a half to knock out Eddie Alvarez and become the first dual-weight champion in UFC history at the Madison Square Garden on Saturday.

McGregor demanded $100m to take on Mayweather in a boxing match, during an event at a New York City nightclub on Tuesday.

Notably, the former American professional boxer retired from the sport in 2015 after a 16-year-long career with a 49-0 record, in which he toppled big names including Filipino legend Manny Pacquiao.

"Much respect to Floyd. He is 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," McGregor was quoted as saying by the ESPN.

"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 UFC champion also had hinted about a possible fight with boxer earlier in August during which he said Mayweather has been trying "come up with the $100 million cash he needs to fight me".

Speculations are rife that the 39-year-old would make it back to the ring to fight his arch-rival Pacquiao, who has been vocal about a re-match.

Things got heated up when Mayweather watched Pacquiao overpower his compatriot Jessie Vargas and clinch the WBO welterweight title after coming back from retirement, from the ringside at the Thomas and Mack Centre in Las Vegas earlier this month.

However, Mayweather has stressed that he is not thinking about coming out of retirement and fight Pacquiao or anyone else.

"A lot of fighters in the sport of boxing may want to retire, but they have to fight because they have to. [But] I don't have to fight," Mayweather said on Wednesday, as quoted by the USA Today.

"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."
