"My way, my rules," Floyd Mayweather said about a potential fight against Khabib Nurmagomedov. But that's not sitting well with Dana White whose fired back.
Mayweather, who appears to be competing in a bout on New Year Eve in Japan, is still open to facing Nurmagomedov though only under boxing rules.
"They came to me talking about the Khabib fight," Mayweather said.
"Khabib called me out, I didn't call Khabib out. They said it has to happen in the octagon and I said.
"You just tell me where Khabib has made nine figures before in the octagon. If he hasn't made nine figures, he's not the A side. I'm the A side, so if you guys want the fight to happen, you must come my way. My way, my rules," he added.
However, the UFC president has insisted any fight has to be inside a cage.
"The answer is 'no.'," White told TMZ in response to Mayweather's proposal to box Nurmagomedov.
Before referencing Conor McGregor's venture to the boxing world.
"He's gonna have to come here and get his ass whoopin'. We did that last time. You gotta come here this time.
"Every time he wants to box. You wanna fight? Want to make 150 million? Come over here and get your ass whooped."
$150 million dollars for an MMA fight - fancy that, Floyd?
The 41-year-old will be in action before the years out in the shape of a exhibition against Tenshin Nasukawa.
Whilst the rule set has yet to be ironed out, we do know that's it's going to be a 'little boxing exhibition' for '9 minutes'. Well, that's according to the man himself.
"It's a no-brainer. Just because I'm retired from boxing. I still make appearances worldwide and make a ton of money," Mayweather said about his on-off-then-on-again Japanese outing.
Nasukawa then Nurmagomedov...? Watch this space.
