Attended the Roma v Udinese on Sunday night game. Pre booked tickets a few days earlier for seats in Sud lateral stand, which neighbours the flag waving, full voiced Roma fans in the Sud stands.
Great, if distant view of the game which was almost secondary to the powerful and continual singing from the fans, orchestrated by the PA.
Points for visiting fans. Nearest Metro is the A line stop for the Vatican and then a good half hour walk. Food stalls available nearer the stadium. One specialised in cold chips ( but would heat them on request!). Take your ticket and ID as you will be checked, bag searched and frisked prior to entry. Food and drink inside very reasonably priced but expect long queues.
Toilets defy logic: one narrow entrance to enter male (turn left) and female (turn left). That was one issue contributing to congestion but to compound matters, to exit the toilets you return down the same narrow corridor! Expect close physical contact with accompanying pushing and shoving.
Atmosphere generated by the swaying, singing crowd was one of the best we have experienced attending a game. Just go prepared for security checks, long queues and a decent walk to and from the ground.
