With this current level of the performance and having success things are clearly indicating we will have renewal of contract for the De Rosie because no one was expecting success like this and change like this which will bring success and now chances are high for them to jump into top four which will be surely big slap on José Mourinho and his tactics which were not allowing these players to perform at their best level but De Rosie done this all, and now they are having just 3 points difference from the fourth spotted Bologna which can be checked in coming weeks as Roma is improving their performance.
Their performance against the Brighton was really impressive because they score too many goals and concede nothing which bring another good chapter and now chances are high for them to have another impressive end of their season into Europa Cup after losing final in last season.
I do agree that he should be getting a contract that will be at least one more season, maybe even longer than that. This dude is on the verge of taking this team to Champions league, a team that would miss conference league without him, going to champions league with him could be the biggest change a single manager change could ever do, I think that only happens in football manager games or something, in real life a team doesn't become THIS much better with manager change, sure a bit maybe if they are lucky, but not this much.
So he should get at least one more year contract, multiple years if possible as well. I think that is why he is going to stay, plus imagine him building a team around his own system, instead of taking someone else's team.
