I understand that Daniele De Rossi hasn't spent much time at Roma for us to be able to analyze his performance for the club but until he wins a trophy for Roma and also maintains a good form for the team then we can rate between him and Jose Mourinho who did better for Roma because regardless of the fact that Mourinho didn't do much better for Roma but breaking a 14 years old history for the club by winning a trophy for them is a very remarkable achievement for Roma so Daniele De Rossi needs to show himself this coming season now that he will be fully in charge of the team from the beginning and not like last season when he inherited the team from Jose Mourinho however, there is this confidence that comes along with a coach starting the season for a club and i assume De Rossi will maintain such confidence but that will be until the season starts and he is able to prove himself for the team.
I think Roma will remain stagnant under De Rossi and expectations are no better when the team is managed by Jose Mourinho. So what do fans expect other than winning trophies of course not, all fans really want their team to win trophies as proof of success in the competition.
This season De Rossi will control the team fully from the start, but sorry I feel pessimistic about his performance. And it is very possible that the most realistic target he can get is only up to 5th place and or worse than that. In addition, Roma management also does not dare to spend a lot of money to recruit several players who have a high level so it is difficult for anyone to make this team develop.
