Brighton are hosting Ajax in the Europa League in dire need of a win, having lost and drawn their opening two fixtures.
But trouble has marred the contest before a ball has even been kicked with fans clashing with police outside Brighton train station.
Fences were smashed over while police tried to keep both sets of fans from fighting one another in footage that's gone viral.
It showed at least one police officer down on the floor as others brandished batons to keep the attackers at bay.
