Roma sporting director Monchi has issued a plea to supporters of the Italian club to set a good example ahead of the Champions League semi-final second leg.
Over 3,000 Liverpool fans are expected to make the trip to Rome, in hope of seeing their side book a place in the final of the competition in Kiev on May 26.
The Reds' 5-2 victory in the first leg was overshadowed by an incident before kick-off, when supporter Sean Cox was left in a coma after being attacked outside the stadium by a group of Roma fans.
Now Monchi has urged supporters to set an example over the next few days, and show the club in a better light by proving a culture of widespread violence does not exist.
"We are facing a unique game," Monchi said.
"The history of this team says only twice before have we had this possibility - in 1984 and now.
"I'd like Rome to be decked out in yellow and red, and for all the fans to hang banners on their balconies to show the world that Rome supports Roma.
"There's a lot of talk about violence right now, so let's show everyone that Roma fans are not violent."
The Roma chief went on to pay tribute to injured Liverpool fan Cox, and pray for a quick return to health for the 53-year-old.
"Football and life are two different things in this case, I am very Catholic and I pray for him and his family.
"We are human beings, I hope he can come back to cheer for his team."
In order to have a chance of progressing to the final Roma must repeat their heroics of the previous round, when a 3-0 victory was required to overturn the margin against Barcelona.
An away goal by Jurgen Klopp's would leave the Italians needing to score five to win the tie.
