(Forward to 33 minutes to see McGregor.)
Conor McGregor recorded the fastest ever title fight victory with a 13 second stoppage of Jose Aldo at UFC 194.
A left hand from the Dubliner, just his second punch thrown, connected with the Brazilian's chin and send him to the canvas.
Two hammer fists later and John McCarthy stopped the fight.
Afterwards, speaking to Joe Rogan, McGregor cited 'precision and timing' rather than power as the chief factors in his win.
