McGregor ‘ain’t never gonna be the best’

Diaz lays into McGregor.

He’s not [great], though. On paper, he’s not. Who are the 145-pound fighters who he beat up? Nobody good, in my opinion. Just a lot of commercials and advertising. How many black belts has he tapped out? When he was talking shit back-and-forth about fighting Floyd Mayweather…like, you have already lost to two guys who are not on a legitimate level. That just tells me, look, you ain’t ever going to be the best. You already lost to two f-cking guineas. I ain’t ever losing to somebody who lost to some f-cking little Irish land guineas. That’s fact, that’s on paper. And in gym, you can see what kind of work he has put in. He ain’t working with nobody — he ain’t working with no black belts. Has no legitimate trainer.
