It's been four months since Floyd Mayweather and Conor McGregor squared off in what's become the most lucrative fight in the history of all sport.

Two of the biggest talkers in the game finally walked the walk last August as Conor McGregor - the first-ever dual weight champion in UFC history - took on Floyd Mayweather - an undefeated five-weight world champion boxer - in his first ever boxing match.

It sounds quite ludicrous put like that, doesn't it? Nevertheless, it drew big box office business and neither man has been seen fighting since.

Mayweather has seemingly retired with a handsome 50-0 record, whereas McGregor is fully expected to finally defend a title in the UFC upon his comeback.

Most fans expected McGregor to take on interim UFC lightweight champion Tony Ferguson, possibly at UFC 219 on December 30, but it seems as if that fight isn't close.

Because of the Irishman's star power, he seems to be linked with mega fights rather than title deciders. One such rumour that surfaced last month saw reports that a deal to fight Manny Pacquiao was close.

While UFC president Dana White moved to squash those rumours, longtime UFC announcer Bruce Buffer - brother of famous boxer ring announcer Michael buffer - told TMZ that he has had some contact with Pacquiao's people.

Buffer said: "I’ve had some of Manny’s friends call me and say, 'Can you talk to Conor’s management?'"

"I told 'em, 'You guys know who to call -- call the right people.'"

The 39-year-old Philippino is undoubtedly past his prime, but he is a legendary boxer none the less and the only eight-division world champion ever.

Buffer did hint that Pacquiao has experience beyond the boxing ring and McGregor has already said he wants his next fight under MMA rules, so could we get Pacquiao inside the octagon? Buffer says Pacquiao has been trying to get the bout for six months.

It would be good to see the shoe on the other foot after McGregor went into the world of boxing a relative novice; what could he do to someone stepping into his domain?
