Following Conor McGregor’s random social media rant on Monday, his current rival, Nate Diaz, has chimed in with a very simple response.

On Monday, McGregor commented on a photo of Diaz that showed the younger brother looking quite large for a 145-pound champion to be fighting. McGregor, in typical fashion, wasn’t impressed.

In fact, he went on to claim that he would “school” Diaz in a rematch and spoke about how he “swept and controlled” him on the ground at UFC 196.

Diaz, also in typical fashion, posted the following brief response:

McGregor-Diaz II was originally scheduled to headline UFC 200 in an immediate 170-pound rematch of their UFC 196 fight, which Diaz won via submission. The fight was pulled, however, when McGregor refused to take part in his promotional commitments around the fight and Diaz refused to fight anyone else on the show.

Headlined by Jon Jones vs. Daniel Cormier II, UFC 200 is scheduled for Saturday, July 9, 2016 at the brand new T-Mobile Arena in Las Vegas, Nevada.
