Conor McGregor is seemingly back in his trash-talking element as he prepares for his octagon return. However, it isn't fighters but renowned MMA coaches around the world who have become the target of McGregor's latest rant.Georges St-Pierre's coach Firas Zahabi, known as one of the best minds in the game, was labeled a "douchebag" by 'Notorious'. Kamaru Usman's coach Trevor Wittman, Khabib Nurmagomedov's head coach Javier Mendez, who has produced five UFC champions so far, and Jon Jones' head coach Greg Jackson, all became the subjects of McGregor's foul-mouthed rant.Hailing his own coach John Kavanagh of SBG Ireland supreme, the former UFC double champ wrote on Twitter:"Firaz zihabi is a little douchebag, Trevor wittman is a pad man. Javier Mendez is a fat lick arse kick boxer, Mike brown [ATT] is a smelly prick, Greg Jackson got caught up, the system of coach kavanagh is now shining thru. In years to come the world will know what we have been at. It’s beginning to bare fruit, if you want to train. Train at sbg Ireland with kav. And me.
