But McGregor has poured cold water on that possibility.
Floyd Mayweather's money-spinning clash with Conor McGregor generated 4.3 million pay-per-view buys - making it the second biggest fight in PPV history. A real fight. What's a real fight?
"What about Pacquiao? Conor, would you fight Pacquiao?" a TMZ reporter asked.
McGregor, however, is under contract with the UFC and the organisation's president Dana White shut down any chance of that happening.
"But if you're going to do boxing rules, the boxer's gonna win 99 and a half percent of the time".
Although the Mayweather-McGregor pay-per-view total is nearly double the third biggest fight of all time, the 2007 bout between Oscar De La Hoya and Mayweather which had 2.48 million buys.
The total global revenue from the event including ticket sales, sponsorship and worldwide distribution exceeds $600 million, which-along with Mayweather vs. Pacquiao- is among the largest for a single-day sporting event of all time.
While signing autographs for his fans, McGregor was approached by TMZ Sports.
"The remarkable results are all the more impressive considering that the planning, marketing and execution took place across a span of just 72 days from the initial announcement to fight night". Then there were McGregor-Pacquiao murmurs. "He's not that great a boxer, and I think we all saw that". It is OK with both of us.
