Probably.
The video, shot in Croatia on Saturday night, purports to be footage of soccer legend-cum-legendary shitshow Diego Maradona engaging in a street fight.
It was reported that the Argentine was in a Dubrovnik nightclub getting it in that night. And though the YouTube is blurry, you can make out a very Maradona-like figure when he steps into the light, and a voice that rings out pretty clearly to those familiar with his past exploits. The calls of "Diego! Diego!" also lend some evidence.
And I mean...this is Diego Maradona we're talking about. This is what he does.
