We'll see if our new hero coach, so praised by the fans, will be able to stem a somewhat unbeatable Inter side.
I see it as really difficult honestly, but let's let the Roma fans dream

maybe their dream will come true
That may come true, but I think Roma will definitely have a very hard to beating Inter.
Roma fans can of course dream that their team can beat Inter, but Inter's performance so far is much better than Roma. Inter have had a good run this season as the favorite team to win Serie A, but that doesn't mean Roma can't beat them.
In the next two matches, Roma's schedule tends to be easier than Inter. Roma has the opportunity to prepare their team well ahead of the match against Inter, while Inter will have to struggle against Fiorentina and Juventus before visiting Rome. There is a chance that Roma will win, but we'll just have to wait and see.
I wouldn't say it's a dream for AS Roma because after all they have a chance to do it, although maybe their chances are not bigger than Inter Milan.
We'll see whether De Rossi will bring fresh air to AS Roma or not. I won't rate his first match with AS Roma, because the time he had was very short so he didn't have much time to think about a very mature strategy with a very short introduction to the squad.
It is clear that AS Roma will have difficulty because Inter Milan this season is very strong, it is not easy to beat them.
