Conor McGregor is getting under the skin of Dustin Poirier ahead of their mouthwatering clash at UFC178 in Las Vegas this Saturday.
Both fighters weighed-in in front of UFC Officials yesterday and when they met in the hotel lobby, you could cut the tension with the knife.
McGregor, sporting a very flashy pair of sunglasses, immediately began staring down his opponent causing the unimpressed American to leave the room.
"I've never dislike a guy as much that i ever fought," Poirier said as he left the hotel.
"There's a time to be professional. In the lobby with your crew there, f**king jack**s, he's new to this game but he'll learn, he'll learn."
