1st game, 1st win for De Rossi and now Mou has been already forgotten.
Mou may go to Napoli next year.
We cannot judge De Rossi by his first match because most coaches are doing well in their first match.
I don't know why Roma sacked Mourinho because I feel that he tried for them last season by winning the UEFA Conference League for them, and he has improved after their poor start of the season; nevertheless, the management knows exactly what they want, and I hope this new manager perform well to the management's satisfaction.
I don't think Napoli will change any manager soon because it's not been long since they changed manager if they decide to sack the new manager. it may affect the team's performance.
You made good points and that's completely right because we can't say anything about De Rossi and Roma yet because he is new to Roma and he couldn't even have any effect on this team since he joined there but he started the first game with a win and let's say De Rossi was lucky enough to have good start in Roma but Hellas Verona is not a hard and strong team and maybe Roma with Mourinho could even score more goals and have better performance in this match.
In my view, Roma fans will forever remember what Mourinho brought to the team, something they had never experienced before Mourinho arrived, so there is no way for the fans to forget it. De Rossi has recorded a sweet victory in his managerial career, and it will also be recorded in the history books by their fans, but forgetting Mourinho services in one match would be wrong. Because the team that was defeated was not an elite team, we need to see what De Rossi can do when facing Inter, Juventus, Milan and other elite teams. There is indeed hope that Roma can perform well in the future, with his understanding of the club De Rossi can easily make things better.
Salernitana, Cagliari and Inter Milan are Roma next opponents, we will see whether De Rossi is able to be a better successor than Mourinho, and erase all doubts about him. I think that if at the end of the season De Rossi is able to bring Roma to a top four finish, then management should keep him for the next season, and see what he can offer the club. Apart from that, the Europa League play-off round is another reference for us to assess whether De Rossi has good managerial talent, so he can become a successful coach in the future. Now under the leadership of De Rossi, Roma plays a 4-3-2-1 formation, unlike usual when coached by Mourinho who liked to use a 3-5-2 formation, now Roma displays a more aggressive game by attacking.
On the other hand, what Mourinho inherited at Roma is no less important, I mean in the form of players like Lukaku. If De Rossi can fulfill this role well, they can appear in the Champions League in two ways, finishing in the top four of the Serie A standings or winning the Europa League trophy starting from the play-off round. Mourinho dismissal was very unfortunate, but club officials did not want to take too big a risk waiting for what Mourinho could offer at the end of the season.
