Liverpool have requested a meeting with AS Roma officials, UEFA, security services and the Italian police to ensure the safety of fans travelling to Rome next week for the Champions League semi-final second leg.
Supporters clashed outside Anfield on Tuesday before Liverpool's 5-2 win over the Serie A side in the first leg.
Two men have been charged in connection with an incident that left a man in a critical condition in hospital.
"Liverpool have sought clarity on issues surrounding the matchday operation since the draw was made and is hoping this extraordinary meeting will provide the necessary reassurances and essential information," the Premier League club said in a statement http://www.liverpoolfc.com/news/announcements/299627-liverpool-statement-roma-travel-champions-league.
"This, if provided, will allow the club to fully inform supporters of the measures that will be in place."
