As Nate Diaz explains, he wasn't actually too keen on fighting Takanori Gomi at first because "The Fireball Kid" was a sort of hero of his and he has so much respect for the former Pride champion. They did fight him, though, and Diaz absolutely dominated him, utilizing a strong boxing game and slick jiu-jitsu to submit him inside the first round.
