Rome is looking better with De Rossi as a coach and they are clearly on a upgrading path, but if you ask me i dont really trust on them, they ahve very bad games were they can make anything as planed.
Maybe they can beat Milan but nothing more after that.
If you watch Milan last game, you will know that Rome will not have their way to beat Milan because they have defenders that will hodl that defense strong until they achieve their goal in this season and, their coach still have more skills to impact to his players to continue performing through out the season.
I know that game can change at anytime but it will be difficult for this game to change for the favour of Rome because I know it will not be easy for Rome strikers to make their coach happy in this game and the Rome players will know that they meet strong team.
