Conor McGregor footage from 2013 shows him doing shoulder strikes used vs Donald Cerrone

McGregor v Cerrone

Brief though it was, Conor McGregor's comeback at UFC 246 has provided enough material for fans to still be poring over it days later.

The Irishman dispatched of Donald Cerrone inside 40 seconds, first stunning him with a head-kick and then letting loose with a series of punches to finish him off.

It was easy work for a £3.8 million purse, to say the least.

Despite lasting less than a minute, the fight has taken its toll on the American, who is now facing a spell suspended while he recovers. 

McGregor inflicted a suspected nasal fracture and is also thought to have broken a bone in Cerrone's face.

The Notorious also surprised his opponent with a series of shoulder strikes. 

In fact, though, never-before-seen footage shows he has been working on that particular move for quite some time, an old video revealing him practising it in training in 2013. 

It was certainly too much for Cerrone.

The move up a division didn't phase McGregor one bit and he's now the only man in UFC history to win via knockout at featherweight, lightweight and welterweight. 

The only real disappointment for him in all this is that he didn't quite get the time in the Octagon he would have liked. 

This was, after all, his first outing since he tapped out against Khabib Nurmagomedov 15 months ago. 

Yet it also means he can look ahead freely to a packed 2020 as attention immediately turns to his next opponent.
