The Irish have taken over Las Vegas ahead of the massive UFC showdown between Conor McGregor and world featherweight champion Jose Aldo.
McGregor has promised the fans a night to remember when the pair clash at the MGM Grand.
Dublin's favourite fighting son - at least in mixed martial arts circles - said: "Respect for me is earned through battle.
"If he (Aldo) shows up and shows heart, he'll earn my respect.
"I can't respect a man who runs, who evades.
"I feel that he feels he's handcuffed and forced into this. He doesn't want to be here. He's confused, he doesn't know what's going on and he can't wait for it to be over."
McGregor, who struggled with a knee injury when preparing for his first scheduled fight with Aldo in July, said he has no concerns ahead of tonight's showdown.
"I wasn't lying when I said I had a hell of a lot of adversity in that last camp," he said.
"That's why you're seeing me in my prime.
"I'm looking good in my body and good in my face," McGregor added.
