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.
Mourinho did well while managing Roma; he helped the team win several titles, but their decision was not bad from my point of view because we have seen several times how he ended his relationship with almost all teams, so instead of spoiling the team completely, he should just leave for good.
De Rossi still has time to prove himself, we cannot judge him with just a few matches; we have to give him a complete season before we can conclude. I am thinking that he can do better than Mourinho because he is a modern coach who can be tactically sound in his half season, and he may bring glory back to Rome.
When I examined De Rossi tactically in the half-season, I also saw that he had a better tactically innovative form than Mourinho, and I think it was much too early to evaluate De Rossi for the half-season. I interpret him as a coach with the technical capacity to bring good success to Roma in the next season.
