Roma managing director Rosella Sensi insists fans of her club will behave impeccably at Tuesday night's Champions League quarter-final second leg with Manchester United at Old Trafford.
Uefa are investigating the scenes at the first leg in Rome when police, in the words of Rome's Prefect of Police Achille Serra, "had to go in hard" to quell trouble between the two sets of supporters.
Sensi, who has day-to-day control of the club owned by her ageing father and club president Franco Sensi, told reporters at the Eternal City's Fiumicino Airport that there would be no trouble in Manchester from Roma fans.
"It's right to call for calm," she said. "But our fans know how to behave whether they are in Italy or abroad."
Referring to the game, Sensi said: "It's a very important game for Roma but we are approaching it calmly."
