Roma received a spectacular welcome at the Stadio Olimpico as they arrived through a cloud of red and yellow smoke, flags and banners for the Europa League semi-final against Bayer Leverkusen.
It kicks off at the Stadio Olimpico at 20.00 UK time (19.00 GMT).
The Giallorossi supporters gathered outside to cheer on their team and the official Roma social media account showed what that looked like both from outside and inside the bus.
Meanwhile, Sky Sport Italia report the club has organised a special choreography for the stands before kick-off that will cover most of the sold out stadium.
There are circa 3,000 Bayer Leverkusen fans present.
