In fact, sending Mourinho off the team was a big risk because he was a very experienced coach. He won the conference league and made Rome a finalist in the European league. That's why Roma made a risky choice and appointed De Rossi as the head of the team. It seems that this change was appropriate and Rome is doing very well this year.
If you look at Roma progress after being coached by Daniele De Rossi, they were able to show quite good changes in the standings because until week 31 Roma still maintained their chances of breaking into the top 4 rankings. Today win also shows how consistent they have been in the second half of the season as they have a great chance of overtaking Bologna.
It is true that Mourinho performed well but his time is over and now Roma is able to show good development with De Rossi. The victory over Lazio was also very important because Roma was able to stick closely to Bologna who were in the top 4.
This season at the top of Serie A there have been quite a lot of changes because last season finalist teams failed to perform well this season, such as Lazio and Napoli.
Under Jose Mourinho this season, Roma weren't considered as one of the teams that'll finish the season in the top four but ever since the club sacked the Portuguese manager and appointed Daniele De Rossi as the new boss, the club have gone from being one of the laughing stocks of the season to become one of the top contenders of teams that are very likely to finish the season in the top four of the Italian Serie A table.
Playing against Lazio today, I predicted that it'll be a win for Roma and that they'll be more than two goals in that game but I wasn't totally correct with my prediction because Roma struggled to win the game and was able to win with just ine goal in the game. However, the win means that Roma have closed the points difference behind fourth placed Bologna to just two points pending the result of Bologna's game against Frosinone on Sunday. Roma I think still have a good chance of making it into the top four of the league table
