When McGregor is asked who would be the toughest challenge for him after the Alvarez fight, Stephens says:
This guy right here (points to self): the hardest hitter. This guy (pointing to McGregor) TKOs people, when I knock people out they don’t f-cking move.
To which McGregor responds:
Who the f-ck is this guy? Who the f-ck is that?
