I have a feeling Roma is going to be very dangerous this year in Serie A.
Aquilani is a fantastic player who will only get better with time. Beside a leftback, GK, and a possible decline of Christian Panucci, I do not see major weakness in their team, and with Manicini, Totti, Aquilani, and Vucinic I feel they have genuine match winners. Inter players may have bigger reputation, but I feel Roma lot is better. Mexes, and Chivu, for instance, at this stage of career, are definetely better than Walter Samuel and Cordova. Ditto for De Rossi.
For me the key to Roma's successful season is that their star players must stay injury free. They do not have the incredible depth of Inter, and sustained absence from any of Mexes, Chivu, Totti, Mancini and De Rossi, I can imgaine the going downhill dramatically. Also I think they are going to tire out eventually with the lack of depth, especially at the back and forward. They better have some good youngsters down on the wings because they are going to need them.
