The 41-year-old who is unbeaten in all 50 of his career fights made the announcement on Monday, but many have been blasting him including rapper 50 Cent after he picked a younger opponent for the bout which will go down on New Year’s Eve.
In a lengthy post on Instagram alongside a photo of Mayweather and Nasukawa, McGregor blasted the American boxer and joked the pair looked like Chris Tucker and Jackie Chan from movie franchise Rush Hour.
He wrote: ‘Is that a tracksuit or a sauna suit Floyd haha w**. is it hot in Tokyo or what’s the story here? that climate change is no joke f*** me hahah
‘What in the f*** is going on here? Who’s this little p**** next to you ? That’s mad s***. Like something out of rush hour 5 or something. Chris tucker and Jackie f****** Chan back in this b****. F****** brilliant. Mad little b****** you are Floyd. Fair f**** to you mate. No lie. F*** it.’
