Aside from Napoli (and Juve obv.), Roma also looks good. They're better defensively, but Napoli is better offensively. Benatia is more solid and experienced than Marquinhos, and that Maicon gamble paid off. Garcia is a very good coach, and finally we're seeing some decent tactics and good team mentality from Roma.
Saw the first half of the Inter game. Catania was better in the beginning of the half, and Handanovic made some very good saves. Mazzarri, as usual, motivated his troops from the sideline, and Inter grew into the game. Mazzarri has already done a great job so far, but they still lack quality on paper. Grit and discipline won't be enough to make the CL. Campagnaro was the third-best CB in the league last season IMO, and he's continuing is good form. He's at his peak and is playing very well.
