Dana White has fired back at Floyd Mayweather's claims that he is seeking a nine-figure pay-day to face UFC star Khabib Nurmagomedov. 

After his stunning victory over UFC-poster boy Conor McGregor, Nurmagomedov wasted no time in following in his rival's footsteps, by calling undefeated 50-0 boxer Floyd Mayweather out for a cross-sport super fight. 

Whilst many immediately speculated over how and when such a bout might take place, plenty of skeptics questioned the legitimacy of the challenge, with Mayweather having previously stated he would only ever fight in boxing. 

Despite a stellar record as an amateur youth boxing champion, McGregor found little joy in his showdown against Mayweather, with the American's hand speed and defensive ability proving too much for the Irishman's timing and power. 

As a man famed more for his incredible grappling as opposed to his upright ability, many former fighters have predicted an even harder struggle for the Dagestani Khabib - although this has done little to stem the excitement amongst both sets of fighters fans. 

Now, however, after Mayweather told TMZ Sports earlier this week that the bout would have to take place under his conditions, or not at all, UFC head honcho Dana White has fired back at 'The Best Ever', giving a few rules of his own.

'The answer is no," White told TMZ. "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."

Whilst his comments are sure to go down poorly with Mayweather himself, White is certainly backed by the vast majority of pundits and former fighters, many of whom have predicted a brutal and quick knockout were 'Money' Mayweather ever to enter a UFC cage.

Stranger things have happened, however, and with rumours having surfaced last year of Mayweather having applied for an MMA licence in the state of Nevada, maybe the legendary Michigan fighter has one last trick up his sleeve.
