UEFA have vowed to implement measures to protect Manchester United fans in Rome in the Champions League this season.
Eleven supporters were hospitalised after the quarter-final against Roma in the Stadio Olimpico last season, the majority after coming under atttack during a police baton charge.
UEFA say there will be changes to the arrangements after the two clubs were drawn in the same group of the Champions League.
William Gaillard, UEFA communications director and special advisor to president Michel Platini, said: “We will take special care of Manchester United fans because we know they had trouble.
“We will tighten up security to make sure they don’t get a repeat of the incident.
“The Italian FA have a new training programme for stewards. It is something that is being applied in the Italian League – we hope that will make a difference. It means we will have well trained stewards instead of riot police.’
United chief executive David Gill said: “There were unacceptable scenes last time we were in Rome and looking at it from our perspective, our fans were blameless.
“We will work with the authorities, with Roma and UEFA to make sure there is no repeat of what happened because we want it to be remembered as a great game on the pitch.”
