That's right, overall I agree with your opinion. In my opinion, De Rossi will need several seasons to bring Roma into a Scudetto challenger club, while hoping that Inter Milan, Juventus, AC Milan and Napoli will experience setbacks. Even for next season, teams like Atalanta and Bologna and Lazio cannot actually be ignored, De Rossi must try hard to improve Roma performance to be better than all Serie A contestants. Expectations for Roma are currently higher, but if you look at the depth of the squad owned, in my opinion it needs to be improved. Roma management must be braver in spending money in the transfer window if they have the ambition to win the Scudetto, or they might just get a ticket to the Champions League next season.
De Rossi has proved that he has the ability to take Roma to greater heights. His performance after Mourinho left showed that he is indeed the right choice for the job. Top-class football is a product of quality players and I think Roma is lacking some key players. For them to compete with these big clubs in Seria A, they need to spend more money in the transfer market. Mourinho once complained that the club was not releasing funds for signing the players he needed. Players like Chris Smalling, Lukaku, and Tammy Abraham to mention a few are not dependable. They need to be replaced by better players. I read that coach De Rossi is targeting Mats Hummels and Andrea Pinamonti which is quite encouraging but they need to do more if they want to compete favorably.
