Boxing supremo Freddie Roach believes Conor McGregor has the skill to knock out FLoyd Mayweather should a fight between the two superstars ever happen.
Roach, who has trained the likes of Mike Tyson, Wladimir Klitschko and Manny Pacquiao, also has the MMA perspective having worked with Anderson Silva and Georges St Pierre, to name a few.
As such, the American is in a unique position to comment on the outcome of the potential fight.
"He is a pretty good striker," the 56-year-old said of McGregor on MMA Fighting.
"The thing is, Floyd is a great boxer. He's really good at hitting and not getting hit and so forth. I think it would take a long time for Conor to get ready for a boxing match, a pure boxing match.
"But, ya know, one punch can change everything. It's the sport we're in. I'm not gonna count him out completely. I think Mayweather is the favorite, yes, but I wouldn't count anyone out. Because he throws, he throws hard, and he's not afraid to throw."
