Nate Diaz isn’t sold on UFC welterweight champion Islam Makhachev.

Makhachev (28-1 MMA, 17-1 UFC) claimed a second belt when he dominated Jack Della Maddalena at UFC 322. He notched his sixteenth consecutive win, tying Anderson Silva’s streak for the longest in company history. He also reclaimed his spot as the No. 1 pound-for-pound fighter.

Diaz and Makhachev were involved in a backstage altercation last December, but the Stockton native insists that’s not the reason why he thinks Jon Jones, not Makhachev is the No. 1 pound-for-pound fighter.

“They just throw sh*t out like that. He’s been there for like two minutes. He ain’t beat no one that great,” Diaz said in a stream with N3on. “The best lightweight ever was B.J. Penn. B.J. Penn beat Matt Hughes, … beat (Georges St-Pierre’s) ass and lost. So when you’ve got sh*t like that and whatever Islam did, that don’t even match.

“Not that he can’t be and won’t be though, but you’re just going to throw GOAT at the motherf*cker when he just showed up on the scene? They think I’m hating because we’ve got our differences, but there’s just sh*t I’ve seen that I remembered forever, and I ain’t seen nothing from them motherf*ckers. I can’t even remember anything but getting bored in all them fools’ last fights.”

Makhachev’s resume includes wins over Dustin Poirier, former UFC lightweight champion Charles Oliveira, and UFC featherweight champion Alexander Volkanovski twice.
