In July the Women’s World Cup Final set records for football coverage in the US with an average audience of 25.4 million - an indication of the rise of the sport's popularity in the country.
Sadly, it seems that football hooliganism has also been imported.
Associated Press reporter Rob Harris caught on camera a breakout of 'fan' violence ahead of the derby between New York City FC and New York Red Bulls.
The skirmish occurred outside the Bello's Pub and Grill in Newark, New Jersey.
Harris reported that glass bottles were thrown alongside punches, before police arrived at the scene.
Bizarrely, the fans started chanting in mockney tones as the fight broke up, in what could be described as a hat tip to the history of English fan violence:

The NY Red Bulls won 2-0 over NYC FC thanks to goals from Felipe and Bradley Wright-Phillips.
