They've had a nice run of games tbf. Brighton win aside, I think they'd be in a similar place under Mourinho.
Doubt it. De rossi is a more attack minded manager and they have been scoring more goals under his management. I've only seen the two games against feyenoord where they were impressive compared to mourinhos games against the same team last year and in the conference final as well.
Irrespective of the style of football that Mourinho adopts or the number of goals scored, I still think Roma probably have a similar run of form under Mourinho. Roma 2-1 Hellas Verona Salernitana 1-2 Roma Roma 4-0 Cagliari Roma 2-4 Inter Milan Feyenoord 1-1 Roma Frosinone 0-3 Roma Roma 1-1 Feyenoord (Roma win on penalties) Roma 3-2 Torino Monza 1-4 Roma Roma 4-0 Brighton Fiorentina 2-2 Roma Brighton 1-0 Roma Roma 1-0 Sassuolo I don't know enough about Serie A but on paper I stand by the point that Roma / De Rossi has had a nice run of games to come in to. I don't know that they'd have beaten Brighton as comfortably as they did but I think they'd have won most of these under Mourinho too.
I also haven't seen many games under both but mourinho was losing some supposedly easy games this season. And fans do care about style so they are winning more and doing it in better style. I did happen to see mourinhos games against feyenoord and de rossi's against the same team and there was a difference in attacking quality in the games
