Conor McGregor has knocked out Jose Aldo in just 13 seconds to take the featherweight title fight at UFC 194.
A swift left hand from McGregor, one of his first of the fight, connected cleanly with Aldo’s jaw and left the 29-year-old on the floor of the Octagon.
“Nobody can take that left hand shot,” McGregor said after the fight.
“Precision beats power and timing beats speed and that’s what you saw there.”
The victory is McGregor’s seventh in the UFC and continues his undefeated streak since his debut in 2013.
The 27-year-old Irish national’s knockout set a new world record for the fastest finish in a championship fight.
McGregor is known for the left strike he used to knock out Aldo, a Brazilian who previously held the featherweight title.
“He threw a cross on my chest which I wasn’t expecting and I threw a punch and he came back with another cross and that was that,” said Aldo after the fight.
“I think we need a rematch, it was really not a fight.”
Aldo had not been beaten in more than a decade and was rated the UFC's top pound-for-pound fighter -- whereas McGregor stood in 12th place.
The swift result shocked many who expected the fight to stretch out over a number of rounds.
