#2. Chuck Liddell vs. Tito Ortiz – UFC 47

The famous UFC combinations we’ve looked at previously were all made memorable by their technical expertise as well as their brutality. Chuck Liddell’s finish of Tito Ortiz at UFC 47, on the other hand, was made famous due to its sheer ferocity.
Liddell and Ortiz had supposedly been good friends and training partners, but that friendship was shattered by the time they faced off in April 2004. At the time, there was no bigger fight in the UFC. The eyes of the world were on this fight like never before.

After a slow first round that saw neither man land many significant strikes, it felt like something had to give in the second.
When Liddell clipped Ortiz with a punch that forced ‘The Huntington Beach Bad Boy’ to retreat, ‘The Iceman’ had an opportunity he capitalized on.
Liddell threw a big left-right combination that forced Ortiz to cover up. Smelling blood, he followed it up with a wild flurry of punches that seemed to be moving at a blur.
The shots may not have been all that accurate, but Ortiz simply couldn’t stop them. Eventually, enough punches got through to slice his face into ribbons, sending him crashing to the ground in a heap.
Announcers Joe Rogan and Mike Goldberg compared the combination to those thrown by Vitor Belfort and Phil Baroni. In reality, Liddell’s ferocity was in a league of its own.
The win was the biggest of his career to that point, and propelled him onto a path that led him to become the UFC’s biggest star for a time. However, it’s arguable that despite all of his success, he never quite matched this combination for its sheer brutality.
#1. Conor McGregor vs. Eddie Alvarez – UFC 205

Conor McGregor’s win over Eddie Alvarez at UFC 205 made history for a number of different reasons. Not only did it make the Irishman the first fighter to hold UFC titles in different weight classes simultaneously, it also cemented him as the promotion’s biggest-ever star.
What’s more, ‘The Notorious’ finished Alvarez with arguably the greatest display of combination striking that UFC fans had ever been treated to.
Despite moving up from 145lbs, McGregor appeared to be the bigger man inside the octagon, particularly in terms of his height and reach. It seemed like his striking was much sharper than Alvarez’s from the off.
He sent ‘The Underground King’ to the canvas on three separate occasions in the first round alone. He saved his best combination for the second round, using it to finish Alvarez for the first time in his UFC career.
As Alvarez, who was already hurt, attempted to push forward, McGregor countered with a picture-perfect series of punches. He landed a left-right, left-right combination that dropped ‘The Underground King’ to the ground.
Alvarez wasn’t completely unconscious, but he was clearly done. Referee Big John McCarthy wasted no time in calling the fight off.
Newer fans of the UFC who’ve only seen McGregor’s plodding performances in his recent losses to Dustin Poirier may wonder what the big deal around ‘The Notorious’ is. Anyone who witnessed this win would never ask such questions.
Simply put, in his prime, the Irishman was a striker like no other. This combination remains the most memorable – and most famous – in UFC history.
