MMA star Conor McGregor wasted no time in letting his former adversary Floyd Mayweather know exactly how he felt about his latest announcement to face Tenshin Nasukawa in Japan on New Year’s Eve.

McGregor who shared a boxing ring with Mayweather on route to getting stopped in the tenth round, took to Social Media platform Instagram to give his brutal opinion saying:

“Is that a tracksuit or a sauna suit Floyd haha wtf. Is it hot in Tokyo or what’s the story here? That climate change is no joke f**k me hahah,” McGregor wrote.

“What in the f**k is going on here? Who’s this little p***k next to you? That’s mad s**t. Like something out of rush hour 5 or something. Chris Tucker and Jackie f**king Chan back in this b*tch. F**king brilliant.

“Mad little b*****d you are Floyd. Fair f**ks to you mate. No lie. F**k it.”
