Roma is one team I admire in the Italian league too, there performance early last season was very poor. I knew they wont be winning the league or competition in the Champions League too. Although they picked up during the end of last season and finished 5th place. In this knew season I am expecting more from the club. From the look of things, I know they are better than last season. I'm looking forward to see what position they will end the season with.
I also have the mindset that Roma will do better this season, there outplay during last season events at the early was too bad although you have said it all, winning the league last season was not achievable by Roma, they were even luck have ended the league in that 5th, it was surprisingly to see them achieve that, at some point last season I was very angry with Roma that made me to stop watching their matches, but am happy to have seen that they started this season very well but that does not mean that they will be the title winner this season, the seaon is still fresh for that, if they eventually continue like this, they mighy likely occupy a very good position in the league table at the end of the season.
