Watch Dana White Guess (and Rate) the Tattoos of UFC Fighters

And while the 10th round TKO made for a more entertaining fight than expected, Mayweather was clearly the more skilled and conditioned fighter and never was seriously challenged by McGregor.

And finally, McGregor has claimed his next fight will be inside the Octagon.

The Irishman collected a rumoured $100 million payday for the scrap, but is adamant it wouldn't go the same way if they stepped into the ring again. I'd like to see him come over to our side and have a knock.

"Just because of how big I am I know I can't stay at welterweight forever and the way you see a guy like Conor getting the two".

'If I had another go with him... If it happens - maybe it will - who knows? I would beat him. I earned their respect and put myself out there. I still converse with Lorenzo daily.

"I was promoter on the Mayweather fight, and we're in current negotiations", McGregor said in a public Q&A in Dublin, according to USA Today.

Because McGregor is far and away the biggest draw on the UFC roster, he has a lot of say in whoever he faces next but it appears that unifying the lightweight title with interim champion Tony Ferguson is the first item on his agenda.

Mayweather, who returned after two years of retirement to take on the Irish mixed martial arts star, bided his time before exerting his superiority from the middle rounds onwards at the T-Mobile Arena. Plus in lightweight, I don't think anyone has held the belt longer than three fights.

Conor McGregor has delivered an ultimatum to the UFC, saying he will not return to the octagon unless one condition is met.

McGregor, who last faced Floyd Mayweather a boxing match on August 26, revealed Tuesday in an interview with Ireland's that he has plenty of options available but now is eyeing a UFC return against Tony Ferguson, who defeated Kevin Lee at UFC 216 on October 7 to win the interim UFC lightweight championship.

Ferguson defeated Kevin Lee at UFC 216 in October for the interim belt, but the card was a pay-per view flop, only pulling in an estimated 120,000 buys according to Bloody Elbow.
