Celtic fans warned not to wear their club jerseys in Rome.
Two Celtic fans were stabbed outside the Flann O'Brien Irish pub on Via Nazionale in central Rome just before midnight on 6 November.
A group of masked Lazio "ultrà" supporters is believed to be responsible for the attack which came on the eve of the Europa League clash between Celtic and SS Lazio in Rome's Stadio Olimpico.
The Celtic fans stabbed are reportedly from Scotland and Germany, and their injuries are said to be not life-threatening.
