Conor McGregor made his usual pre-fight appearance on Conan O'Brien's TBS talk show on Wednesday night. O'Brien is an investor in the promotion, hence the UFC's number one draw's regular appearances.
The Dubliner this weekend faces Khabib Nurmagomedov at UFC 229 in Las Vegas for the lightweight belt.
Asked about the one-time friendliness between him and Nurmagomedov, McGregor brushed it aside.
"There are no friends in this business. I had a fan, originally. The man was a fan and things change. I don't have friends in this business."
McGregor believes the 30-year-old Dagestani fears him.
I saw what I've seen many times when I've looked at that man, his eyeballs turned to glass. The blood rushes from his body and sprints out of his arse. That's what I saw - another man froze.
I believe he has many weaknesses in his game. In the Dagestan region, they specialise in wrestling. The kid wrestled bears when he was a baby, it's part of their culture. I'm under no illusion, he is a skilled wrestler. Of course, in the whole picture, there are many more facets to fighting, a lot more than one single discipline.
I have many weapons to dismantle all styles of opponent and this is just another style of opponent. I believe he's slow, he's flat-footed. His striking is very average and I will look to expose that.
He may have wrestled Dagestani bears but he has never wrestled an Irish gorilla.
McGregor also took the opportunity to promote his new whiskey brand, having a sip of what may or may not have been alcohol.
He also told O'Brien the Irish for whiskey. Though, he did not get the direct translation correct. Uisce beatha means 'water of life.'
"I'm two days away from the biggest fight of my life, so I'll only drink half the bottle.
"We call it uisce beatha in Ireland, uisce beatha means holy water. This is Irish holy water for you, Proper No. Twelve.
