Conor McGregor: Video of his incredible display against Chad Mendes is so good it's gone viral

Conor McGregor showed an incredible amount of heart and courage to come from behind and beat Chad Mendes in the main event of UFC 189.

Back in 2015, McGregor was on the verge of becoming a breakout star in the UFC, with his cocky attitude and exciting style of fighting proving immensely popular with the MMA fanbase.

He was originally supposed to challenge then-UFC featherweight champion Jose Aldo for the title at UFC 189, but after Aldo was forced out due to injury, he faced Mendez for the interim 145lbs belt instead.
