Top 5 UFC knockouts of the decade (2010-2019)

#3 Conor McGregor vs. Jose Aldo, UFC 194 – 12/12/2015

Conor McGregor became a superstar with his stunning KO of Jose Aldo

UFC 194’s main event was built as one of the biggest – if not the biggest – fights in UFC history, as legendary Featherweight champion Jose Aldo put his title on the line against the fast-rising Irish superstar Conor McGregor, but few could’ve known that the fight would also produce one of the promotion’s all-time great knockouts.

McGregor had been promising something special leading into the fight, but despite delivering the goods up to that point – with five UFC victories to his name including a win over former title challenger Chad Mendes – there were still some fans who felt that ‘The Notorious One’ was all mouth. They were silenced when the fight finally came to pass.

Aldo – who looked more nervous than he’d ever done for his previous seven title defences – came out looking to strike, and in practically the first exchange of the fight, he caught McGregor with a clean left hand. The only problem? McGregor had gotten there first, and caught Aldo with a perfectly-timed left just as the Brazilian threw his own punch.

Aldo went down face-first and a pair of hammer fists sealed the deal. Not only had McGregor done exactly as he’d promised by dethroning the longtime champ, he’d also finished him off in just 13 seconds, handing him his first loss since 2005. On this night, a superstar was well and truly born, and ‘The Notorious One’ hasn’t looked back since.
