The performance of the Roma team under Mourinho was not as good as expected. Moreover, Mourinho's relationship with the management was not good. This is why Roma management fired a coach like Mourinho. De Rossi is not experienced enough. But that's not to say Roma won't improve with De Rossi. Maybe the Roma team players will be able to adapt themselves well to De Rossi's match strategy. Every coach has his own unique strategy.
De Rossi might be able to stabilize the team. But the Roma team is not strong enough. Roma management should definitely take necessary measures to strengthen their squad. If the squad is not strong, it is not possible to get consistent good performances from the team.
Roma must thank Mourinho, he has been able to deliver a major title that has never happened before. The Special One was also able to increase the number of spectators at the Olimpico, thereby increasing club traffic again. I think Roma management was wrong to fire him. The transfer of coaching staff to De Rossi also did not improve the Giallorossi's performance, in fact there was only a setback compared to before. I am pessimistic about this team next season and it looks like it will be difficult to compete in the top five.
We have to admit that Mourinho has instilled a winning mentality in every Roma player, so that De Rossi can easily manage Mourinho legacy players. It is not easy to build a squad that has good bargaining value, Roma before Morinho arrival could not even win any trophies in European competitions. However, Mourinho still needs to be appreciated, regardless of the management and club officials assessment of him.
De Rossi is a new hope, but without adequate budget support he will suffer the same fate as Mourinho, or even worse. Of course we'll have to see how he performs next season, before forming any further opinions on him. But if you look at the presence of Inter, Juventus, Napoli and Milan, it seems that De Rossi will find it difficult to bring Roma to finish in the top four of the standings next season.
Expectations for De Rossi are now increasing, he has become a new hope for Roma fans. It is not impossible that De Rossi can lead Roma to become champions next season, but with the ammunition he currently has, the possibility is very low.
