Conor McGregor has named the ‘toughest’ opponent he has ever fought as Nate Diaz, with whom he traded wins in 2016.
McGregor’s professional record as a mixed martial artist stands at 22-6, with Diaz having been responsible for one of those defeats – alongside Khabib Nurmagomedov, Dustin Poirier (twice), Joseph Duffy and Artemij Sitenkov. And Diaz was the toughest of them all, according to McGregor.
