Nate Diaz has hit back at Justin Bieber after the Canadian pop star criticised Diaz's style following his second-round defeat of Conor McGregor at UFC 196 on Saturday.

The 30-year-old condemned Ireland's McGregor to his first-ever UFC defeat, forcing him into submission with a rear-naked choke, and Diaz was clearly unimpressed with Bieber's reaction to his huge win:

Diaz's artwork came in response to the 22-year-old's earlier post, in which he toasted McGregor and criticized the Stockton, California, man for his "terrible" style in the aftermath of Saturday's fight.

BT Sport UFC provided video of Diaz's impressive finish in Las Vegas:

It was a significant shock as the American was most certainly the underdog ahead of the welterweight bout.

Diaz had been drafted in at late notice after Rafael dos Anjos dropped out of his lightweight title fight with McGregor due to an injury just days before the event.

However, Diaz came away the victor, having humbled one of the biggest stars in MMA.

McGregor will have lost few fans, though, and he is still the UFC featherweight champion following his 13-second knockout of long-term titleholder Jose Aldo at UFC 194.

A return to the featherweight division is the likely next step now for McGregor, and Aldo has already called him out for a potential rematch at UFC 200.

As for Diaz, he has far more options open to him after a potentially career-defining win.

UFC President Dana White said after Saturday's fight that a clash between Diaz and welterweight champion Robbie Lawler "would make a lot of sense," per ESPN (via's Elias Cepeda).

However, Diaz is traditionally a lightweight and may wish to drop down again when he next steps into the Octagon, perhaps even for another shot at dos Anjos, to whom he suffered a unanimous-decision defeat in 2014.
