Two Brighton fans were stabbed in Italy ahead of their club's Europa League fixture against Roma.
Sky Italy reported the men aged 27 and 28 - who were also robbed during the attack - were taken to hospital to be treated for their injuries, which were not believed to be serious.
The men were able to take refuge in a nearby restaurant after being stabbed, where an employee called the emergency services.
It is understood they have since been discharged from hospital and that English police liaison officers and the British Consulate are providing help and support.
One of the fans was pictured entering the Stadio Olimpico for the round of 16 first-leg match.
A spokesperson for Sussex Police said: "We can confirm our dedicated football officer PC Darren Balkham is in Rome to work alongside our Italian counterparts and European partner agencies."
Italian newspaper La Repubblica reported that two men were attacked and stabbed in the thighs before being robbed by a masked gang of around seven people in the Monti district of the capital.
The Foreign Office have told Sky News: "We are providing assistance to two British people who were attacked in Rome and are in contact with the local authorities."
There were also issues during the game in Rome with Brighton claiming bottles, coins and lighters were being thrown by home fans into the away end.
A Seagulls statement at half-time on X said: "We are aware of the bottles, coins and lighters being thrown by home supporters into the away end. We have reported to UEFA and Italian Police and requested immediate action be taken."
Around 3,500 Brighton supporters have travelled to Rome for their Europa League last-16 first leg on Thursday night, which kicks off at 5.45pm.
The club had warned fans in advance of the dangers of street crime, saying: "Street crime, including pickpocketing, can take place in Rome. Be vigilant, take sensible precautions and have valid travel insurance."
Seagulls supporters attending the game have been advised to use a free shuttle service to get to and from the Stadio Olimpico.
Earlier this season, 58-year-old Newcastle fan Eddie McKay suffered stab wounds when he was attacked in the Navigli area of Milan the night before the Magpies' Champions League clash with AC Milan at the San Siro Stadium.
