Ferencvaros, often dubbed Hungary's most feared football fans, kicked off a huge melee with AZ Alkmaar supporters in their tense Europa League clash on Thursday.
The large group of men managed to get as close as possible to the AZ Alkmaar fans before punches were thrown - sparking chaos in the stands.
In 2023, hooded AZ Alkmaar yobs smashed down barriers to storm their own main stand via two sets of stairs and attack West Ham supporters.
There were also clashes between West Ham and AZ fans ahead of kick-off, who again were masked as they caused mayhem on the streets of Alkmaar.
AZ Alkmaar away days are also known to English fans as a potentially volatile trip.
