Brighton and Hove Albion fans were stabbed, beaten and robbed in Italy before their 4-0 defeat to AS Roma in Europa League last 16 clash.
A 27-year-old and a 28-year-old, believed to be Brits, were assaulted by a masked gang of thugs and found by cops with stab wounds on their thighs.
Police arrived outside a restaurant in Rome after hearing reports of fighting and found two men injured and bleeding on the street, Italian media reports.
Cops were called to the Monti district after a waiter reported the chilling attack.
The two fans had been beaten up in the street by “six of seven people wearing masks” just after midnight on Wednesday evening, a police spokesman said.
The pair were also robbed of their bags which had their wallets and documents inside.
The thugs sharply fled the scene before the cops could arrive.
The two injured men were then taken to a local hospital.
Meanwhile, footage has emerged appearing to show Aston Villa fans being attacked by Ajax hooligans at a train station.
A small group of Brit supporters were reportedly set upon ahead of their Europa Conference League match in Amsterdam on Thursday night.
The footage shows one fan struggling to stand up after appearing to have been knocked to the floor – while several other men can be seen swarming another Villa supporter.
After suffering multiple blows to the head the defenceless fan falls to the ground, while the hooligans continue to kick him.
One of the men then turns around and throws a flying punch at the fan who had only just found his feet.
The footage then ends abruptly and it is currently unclear what ensued afterwards.
The four Dutchmen were caught acting violently on CCTV – in a rampage which left one fan with “life threatening” injuries.
The Dutch gang-of-four were also banned from every UK football ground for six years.
