5 fights of Conor McGregor which showed his left hand prowess

#1 Jose Aldo

Conor McGregor's 13-second KO of Jose Aldo

Number 1 is, you guessed it, that famous 13-second knockout of Jose Aldo. Similar to the upcoming one, this was also touted as the biggest fight in the history of the UFC.

Aldo came into this one undefeated in 10 years, but that didn't stop McGregor putting him away with the left hand, the first of which he threw, again showing his deadly one-punch knockout power. Can 'The Notorious' recreate this on October 6? Either way, it is sure to be a classic and cannot be missed.
