Yup, Juventus are ahead of the competition by some distance, it would require a major fuck up for you guys not to win the league, but if I were to predict who will come second best, I'd say Napoli.
Roma are a bit of an unknown, theres a lot of uncertainty riding over their new coach Rudi Garcia and whether or not he'll work there. They made some good signings, but its yet to be seen how well they'll adapt.
