Mourinho's 3 seasons in Serie-A as AS Roma coach, it can be said that AS Roma's performance is stable under Mourinho's direction, but only stable and does not show any improvement. Well, maybe AS Roma feels that they have given Mourinho enough opportunities and prefer to replace him. Actually there was an improvement when De Rossi was appointed to replace Mourinho, but it is quite unfortunate that in the new season De Rossi declined.
Either AS Roma is not very patient or what, because they made a decision at the beginning of the season when usually a team has not found their best form. Now AS Roma must start again from 0 with their new coach.
That's over and I think there's nothing wrong with Roma's management's decision to fire Jose Mourinho because at that time there was no more positive progress so the management had to take that big step.
Now Roma has a new coach, Roma's management has appointed experienced coach Claudio Ranieri to be able to handle the Roma team this season and I think that's the right step because as we know that Claudio Ranieri is a coach who is quite experienced in Serie A so he has a big chance to be able to improve Roma's performance.
