Every game is a massive game for Roma. Seats are always sold out, which is not something to take for granted in Italy, especially in the second biggest stadium in italy, and especially when you end up 6th every year in the domestic league since a few years. As for the atmosphere, this is not surprising for a Roma game in EL.Overall Rome was the best I guess. Its easily the best city out of all the others.
I was stunned how seriously they took us and how much respect they had. Bit different to when we go to Liverpool, city or arsenal and half the stadium is asleep. And you get zero respect for supporting a smaller team.
This felt like a massive game for them.
Brighton had a good reputation because of your last seasons and De Zerbi's reputation (not sure if deserved), but it's the EL that we take seriously, not necessarily the opponents.
