Mixed martial arts fighter Conor McGregor apparently took a dim view of an offer of assistance coming from Floyd Mayweather, a boxer who once defeated him, and used harsh language to convey his emotions.
"F*ck the Mayweathers, except Senior and Roger. There is no peace here kid. Step up or step down," McGregor tweeted.
Earlier, Mayweather offered his training facility to McGregor to help the latter train for the upcoming match with the current UFC Lightweight Champion Khabib Nurmagomedov.
"I know that UFC has a training facility, but we’d like him to work at the Mayweather boxing club," he told TMZ sports.
McGregor’s response, however, led many Twitter users to remind him of his boxing match with Mayweather, which ended with McGregor’s defeat by TKO.
The highly-anticipated McGregor-Nurmagomedov bout, which will see the Russian champ defending his title, is scheduled to take place on November 3 in Las Vegas.
