UFC flyweight champion Demetrious Johnson is picking Conor McGregor against Floyd Mayweather, and wants to see “The Notorious” fight the Gennady Golovkin vs. Saul Alvarez winner afterwards.

The UFC’s pound-for-pound king is siding with Conor McGregor to top Floyd Mayweather, and he would like to see the UFC lightweight champion stay in boxing after he pulls off the huge upset.

UFC flyweight champion Demetrious Johnson recently spoke to TMZ about the mega-fight and his prediction.

“I’m riding with Conor,” Johnson said. “I think Conor, he can probably get it done sooner if he goes out there being ferocious, but I’m going with Conor. I think Conor’s gonna get the job done.”

“Mighty Mouse” isn’t too sure what McGregor’s immediate future after the Mayweather fight will look like, but he hopes “The Notorious” fights the winner of Gennady Golovkin vs. Saul Alvarez, a highly-anticipated boxing match happening in September, if the Irishman comes out on top against “Money.”

“It’s hard to say. I’ll tell you what: he ain’t gonna make a big check like that in the UFC,” Johnson said. “Hopefully Conor goes out there and knocks Floyd out, and then he can go ahead and fight the winner of GGG and ‘Canelo’ Alvarez. I’d love to see that.”
