Arsenal fans were videoed fighting each other in the stands of the MetLife Stadium during their 2-0 defeat to Manchester United.
United ran out comfortable winners in their third pre-season friendly. Goals from Jadon Sancho and Bruno Fernandes made sure of the victory to maintain their perfect record in pre-season.
Whilst there was a little bit of needle on the pitch between the players, there was even more in the stands. Only, it was two of Arsenal's fans getting shirty with one another.
It's unclear what started the flash point, but a large group of their fans began trading blows with one another before two fell onto the steps of the terraces. The video shows stadium staff doing very little to intervene in the mele until one person eventually appears to assess the situation when the main action had died down.

Two fans, in particular, caught the eye in the footage, as both were left battered and bloodied after the exchange. The pair had been grappling on the steps and left each other with nasty-looking injuries.
Security did eventually arrive once the initial crowd had dispersed, with the fans shown away from their seats, presumably to outside the stadium. All of this unfolded whilst the match was ongoing with the new footage giving a view behind the brawl.
On the pitch, tempers remain cool despite one flash point between Lisandro Martinez and Martin Odegaard. The Arsenal captain took exception to the United defender's challenge on Bukayo Saka, for which he was booked.
