That's quite good odds that well worth a punt. I can see McGregor going in like a mad man going for the knockout in the first few rounds as that is his only chance really but if he leaves himself open like the vids of him sparring show then Mayweather will knock him out easilyMy money's on MayWeather in rounds 1-3 Odds of 15/2
Tenner on, if it loses, oh well only a tenner, if it wins that's a nice 75 quid
