The fight that every boxing and MMA fan wants to see could have come a step closer.

Appearing as a guest on ESPN's First Take, Floyd Mayweather called out UFC champion Conor McGregor and UFC president Dana White to get a deal done for a one-on-one with The Notorious.

Mayweather, 39, retired unbeaten in 2015 and admitted a bout with the 28-year-old Irishman - who recently obtained a boxing licence - is the only thing that could tempt him back into the ring.

"Only thing I'm probably interested in is the Conor McGregor fight," Mayweather said. "I'm a businessman, and it makes business sense. I believe in what me and [adviser] Al Haymon talk about every day - I believe in working smarter, not harder."

McGregor became the UFC's first dual-division champion in November and has previously challenged Mayweather to an MMA fight. However, last year the Irishman had a boxing licence granted by the California State Athletic Commission.

Mayweather also discussed the figure that would need to be stumped up for him to step back into the ring.

"We tried to make the Conor McGregor fight," Mayweather said. "They know what my number is. My number is a guaranteed $100 million. That was my number.

"We are willing to give him $15million and then we can talk about splitting the percentage - the back end - on the pay-per-view. But of course, we're the 'A side'. How can a guy talk about making 20 or 30million if he has never made 8million or 9million in a fight?"

But there could still be numerous stumbling blocks to making the long-awaited fight happen. Last month, McGregor's coach, John Kavanagh, confirmed that the pair are in talks for a potential scrap this year, but because McGregor is under is contract with the UFC, any potential fight against Mayweather would have to involve a co-promotion or the UFC's blessing.

So why is Mayweather so interested in this fight? What do we know about the man and what makes him tick?

Mayweather's History

Born into a family of boxers in Grand Rapids, Michigan, Floyd Joy Mayweather Jr competed from 1996 to 2015 and is widely considered to be one of the greatest boxers of all time.

Undefeated as a professional boxer, and a five-division world champion, Mayweather won 15 world titles and the lineal championship in four different weight classes during his time in the squared-circle. He earned in excess of $800million over the course of his 19-year career

"I had a game plan from the very beginning," Mayweather, 38, said of his career following his final fight against Andre Berto.

"I always knew what I wanted to do - be outspoken, be one of a kind. To be in the sport for 19 years and to be world champion 18 years, I've had a remarkable career.

How Floyd Mayweather spends his money.

"If you put them (opponents) in front of me, we see what they can do. It's all about that IQ. I'm 10 steps ahead of any fighter. I take whatever is your best attribute and take that away from you, make you do what you don't want to do."

Mayweather matched the 49-0 career record set by former heavyweight champion Rocky Marciano. If he was to return to fight McGregor, he would have an opportunity to claim an unsurpassed 50-0 unbeaten record.

Mayweather's Money

Since retiring, he has moved into boxing promotion. It is estimated that Mayweather is worth an estimated $400 million at the beginning of 2017.

Mayweather has previously revealed he has $15million worth of cars that he never drives just sitting in the garage of his Las Vegas home, with his fleet of cars including 16 Rolls-Royces.

He also runs the Floyd Mayweather Jr. Foundation, which promotes education and community outreach in the Las Vegas area, and has donated to charities, including the Susan G. Komen Foundation, Habitat for Humanity Las Vegas and Three Square Food Bank.

Will this fight happen? We're going to have to wait and see but it is brilliant to watch it all unfold and thinking about who might win.
