Never-before-seen footage of Conor McGregor's infamous 13-second knockout victory over Jose Aldo has been released ahead of the Irishman's return to the Octagon against Donald 'Cowboy' Cerrone next weekend.McGregor secured the fastest knockout in UFC title fight history at UFC 194 on December 12, 2015, the night he was able to overthrow Aldo from the top spot and take his featherweight title.This newly released footage, posted by UFC on their official Twitter account, offers a brand new angle to watch the incredible action.As the 31-year-old looks to face Donald Cerrone at UFC 246 on January 18, the promotion is looking to remind fans of his exceptional power, after a disappointing three-year spell in which Conor failed to win a match, not fighting since his submission to Khabib Nurmagomedov in 2018.The 'notorious' KO at UFC 194 can now be seen from over McGregor's left shoulder, offering a new perspective on his perfectly timed left hook which left Aldo down for the count.

Since that monumental win in 2015, McGregor has gone on to become the first UFC fighter to hold two belts at once, box and lose to Floyd Mayweather, and then go on a three-year winless streak.

Results in the cage have remained underwhelming for McGregor, coming off a devastating loss to former rival Khabib in 2018, yet his soaring popularity and bank balance doesn't seem to reflect this.

Ahead of McGregor's return, his trainer John Kavanagh has insisted that he is free from distractions and back to his best, potentially hinting at a career-high performance against the 'Cowboy'.

Speaking to TheMacLife, as per The Sun, Kavanagh said: "With Conor's fight IQ, Conor's understanding of the game, really this training camp is about all of us getting out of his way.

"Provide him with an environment where he can have different looks, different feels and support him where he wants the training camp to go, in intensities and listening to him where he has days where he wants to push hard and days where he wants to slow down.

"It's not so much about us coaches sitting there on a game plan and filling Conor in. Conor knows more about fighting than the rest of us put together.

"I think this is the best he's ever been. And the reason why I'm saying that is because of the consistency over the last few months.

"There's a real return to smiling on the mat, enjoying it, having fun and it's a cliche to say but a happy fighter is a dangerous fighter.

"He just seems really happy with his life and with his training and with the environment we have here, and competing again, and having those exchanges and so on. So I think this is the best he's ever been."

Only time will tell whether McGregor's form is back up to standard, but it's almost certain that the fight will be a good one nonetheless.
