You don't need to think here, just look at the facts: Mourinho achieved 6th place twice in the two full seasons he coached Roma. Against the backdrop of the fact that he additionally won the Conference League and led Roma to the Europa League final, this is a success that will be difficult for all subsequent coaches to repeat.
As for this season, no one knows where Roma would end up with Mourinho. I think you know that every coach has his own views and plans the peak of the team’s shape, focusing on different events in the season, it is quite possible that Mourinho was leading the team to win the Europa League.
It's true, Mourinho's trail has been very long and full of victories. Maybe the players at Roma don't really respect Mourinho so instead of having to continue this and it becomes an internal problem that can threaten the performance of every player from Roma, there is no other choice. apart from changing the Roma coach to Daniele De Rossi.. Each coach has his own characteristics and different achievements. Hopefully Daniele De Rossi can become a great coach and bring Roma to victory in every match they face.
First, we need to understand whether DeRossi is a transitional coach or whether he has outgrown this status. But in any case, whether he stays or they hire a coach with a big name, I doubt that Roma will be able to compete for the Champions League zone, even taking into account the fact that Serie A will most likely retain its 5 spots.
Roughly speaking, Inter, Milan, Juventus, Napoli will take 4 tickets and Lazio, Atalanta, Bologna, Roma will apply for the remaining one with equal chances - so the chances on paper are 25%.
