Roma are the same team as the one in the previous season. Mourinho's arrival still hasn't changed too much in the Serie A especially. They were really successful in the Conference League but they just can't make a big improvement in the Serie A. They actually had a good start but they started a bad form not much time later.
Roma should play more ambitiously especially in big games. They haven't been much successful in such games so far. For example they were really weak against Napoli despite playing a home game. Mourinho made the team play too cautiously and this brought their end. I hope we can see some changes when the league games are back.
