McGregor and Mayweather in heated exchange

Two of the fiercest proponents of contact sports are facing off. Conor McGregor and Floyd Mayweather have engaged in a brawl that seems to have no end in sight.

Days ago, Floyd Mayweather belittled Conor McGregor's victory over Brazilian Jose Aldo, which crowned him as the new featherweight champion of the UFC.

According to Floyd Mayweather, racism in Mixed Martial Arts has propelled Conor McGregor and Ronda Rousey's careers in the UFC. "Racism? It's an open secret, as everyone knows it exists," said 'Money'.

In response, Conor McGregor came out swinging against the controversial former boxer. "(Floyd) Mayweather, never bring race into my success again. I'm Irish. My people have been oppressed throughout our existence and it's still happening," said the lightweight champion of the UFC.

And if that wasn't enough, tired of Floyd Mayweather's attacks, he challenged him to fight at any time. "Floyd (Mayweather), if you want, we can arrange a fight without a problem. You just have to let me know," concluded the Irishman.
