Interim UFC lightweight champion Dustin Poirier blogs for MMA Junkie each week on the road to his UFC 242 title-unification bout with Khabib Nurmagomedov, which takes place Sept. 7 at The Arena in Yas Island, Abu Dhabi. In the fourth edition of “Dustin’s Diaries,” Poirier (25-5 MMA, 17-4 UFC) closes out training camp for Nurmagomedov (27-0 MMA, 11-0 UFC) and reveals how important his tight-knit coaching staff will be to him claiming the undisputed 155-pound belt. * * * * The importance of my inner-circle I don’t listen to criticism from anyone unless I would take advice from them. Unless you’re part of my camp, part of my family, part of something that I respect, and I believe your word and we’re on the same level, or you’re inside of my circle, I don’t take advice from anyone. I went to American Top Team back in 2012, and here we are in a champion-vs.-champion fight about to unify the belts, and my same group of coaches has been there the whole way.
