McGregor responded by posting a cartoon picture of himself holding all three WW titles around his waist, stood over a fallen figure.
Mayweather favorite to win on points but he really should be careful what he wishes for. McGregor is incredibly quick, accurate and powerful. Mayweather wants a boxing match. McGregor will want a war. Starting to get the impression Mayweather is jealous, not of the meager amount McGregor makes compared to him but that Conor has become to MMA what he was to boxing and even further in Conor's case.
This would be the biggest boxing PPV of all time, it will shatter records.
