Conor McGregor's hopes of a rematch with Khabib Nurmagomedov may have been dashed after his rival responded to reports of a second bout by saying "giving me $100 million for me to beat up that idiot again? I don't think that’s rational".

Khabib scored a convincing submission victory in their first showdown at UFC 229 in October 2018, a night that was marred by an ugly brawl between the two warring camps in the aftermath of their fight.

McGregor spent 15 months out of the Octagon following the defeat before returning to earn a first-round knockout over Donald Cerrone last month and the Irishman has spoken of his desire for another shot at unbeaten lightweight king Khabib.

This week, Khabib's manager Ali Abdelaziz told TMZ that Saudi Arabia would be willing to stump up a whopping $100m to host a Khabib fight if McGregor or Floyd Mayweather Jr were his opponent.

However, Khabib – who is scheduled to defend his lightweight belt against Tony Ferguson on April 18 – appeared uninterested in facing off with McGregor again.

"Why do I need that kind of money? There are so many organisations for example…there's not only football for the blind, there's Sambo and other sports," he said when speaking to reporters in his native Dagestan. 

"Let [UFC] give it to them, if they don't know what to do with the money. But giving me $100 million for me to beat up that idiot again? I don't think that's rational.

"What'll happen after a fight – no one knows. I don't worry about it. I'm surprised people even question me about a rematch.

"It seems that people want to continue the festivities after the fight. Everyone saw what happened in the octagon. I controlled the fight every step of the way.

"I did everything I wanted to do to him – he even gave up. How can we discuss a rematch? We can only talk about continuing festivities and making money."

Khabib said his only priority for the time being is focusing on Ferguson.

"I have a fight on April 18," he added. "A very serious fight. For the past month and a half I've been consistently training day and night. 

"I've gotten myself in good shape, to where I'm supposed to be 70 days before a fight. I feel great."
