Police officers on horses eventually managed to break up the brawl by using batons as one man walked away with a nasty gash down the side of his face.
Following the fights, a police spokesperson confirmed that the knife injury sustained by one supporter was not thought to be life-threatening.
The Metropolitan Police released a statement on the incident that read: 'At around 16:42hrs officers became aware of a large group of males fighting in the Hawkstone Road area.
