when's the last time Benitez won a league title, a decade ago? 2009/10, 2010/11 all these seasons Juve started the season in style, looking like the shit, but once that first wave of enthusiasm was gone the team crashed. I'm not saying Napoli is going to crash, but a completely revamped side with a new coach can look intimidating during the first months, the hard part is to keep it up. I'd say all these reinforced teams - Fiorentina, Napoli, Roma, Inter - will eventually slow down, none of them have the quality and depth to sustain their form in the long run.
