I actually think they will be better than last season once the season actually starts. They just need some depth.
But last season they had no Nesta, lost Rino for most of the year, Ronaldinho did not play much, Kaka was injured a fair amount, no Tiago Silva, No Borriello
Now they have Nesta back and if he stays fit that is a huge boost to them, They borught in a great partner for Nesta in Silva, Ronaldinho seems to be more serious this season and will be vital, Borriello is fit and if he can play like he did the year before last he will be important, Rino is fit too. Also Flamini seems to have settled towards the end of last season.
Once they get one of their goal keepers back from injury, bring in a center forward (which will defn happen) and possibly sign a mid and defender. I think they will have a good year for them and come 3rd
