Conor McGregor celebrated his ESPY Award for "Best Fighter" on Instagram. An award he won despite being beaten. What are you is you're the guy who beat the "Best Fighter?"
Anyway the brash fighter also called out his haters with a warning, "I am deep in preparation to come and take out everyone that has spoke my name in vain. I will get you all."
That's a promise I think he'll find difficult to keep.
