The rivalry between Manchester United and Arsenal is renowned for being feisty but it appears the tension spread from the pitch to the stands during their preseason friendly Saturday night.
The Gunners fell to a 2-0 defeat to the Red Devils at the MetLife Stadium as they continued their preseason tour Stateside after a 5-0 trouncing of the MLS All-Stars earlier in the week.
It was a physical encounter, typical of the fierce rivalry that has existed between the two sides, but the tension also appeared to boil over in the crowd.
