Yes, since the arrival of Jose Mourinho to AS Roma, they have been able to show improvement and one of them has won the Conference League title, and they can continue that if they are not confronted by Sevilla in the Europa League this season. But their journey now can be said to be even better than before. But before that, they have to take advantage of the competition break to improve the team to be able to compete next season.
Next season will not be easier for anyone, including AS Roma, because other teams will also make improvements during this break. I think that AS Roma have just been unlucky this season in the Europa League so they failed to get a trophy in the Europa League even though AS Roma still has the chance to try again in terms of getting a trophy next season in the Europa League even though they still have to fight harder than this season.
From this season's failure to win a trophy, I'm sure Mourinho will fight even harder to improve Rome so that next season he can be even stronger and sharper in defense and attack.
This can be a lesson for Mourinho so he can use better strategies and players next season.
Anyone who says Roma will not be able to get the same opportunity as this season then it seems he does not know the development of Rome while under Mourinho's care because so far while Mourinho has held many significant developments have been obtained by Roma.
