Two sets of ultras square up to each other in a remote woodland area on the outskirts of Rotterdam.
One is dressed from head to toe in black, the other distinguishable in white. Both are wearing gloves and hurling abuse, with the word 'hooligans' heard clearly as both groups bounce on the spot, ready to launch into a brutal assault.
This was the scene caught in shocking footage which took place last Saturday during an arranged 'revenge' fight between two rival gangs from France and Holland.
The 19 Dutchmen dressed in combat gear felt they had an old score to settle, dating back to November 30, 2006.
