This is an excellent year for Napoli even the bookmakers say so, I would probably bet on winning the championship but Serie A is a tough tournament with many surprises until the end. The race for the Scudetto is still far off and this year there is also the World Cup which can change the tide.
I'm not too sure Napoli will come back as mighty as before the World Cup break, their steps will be very heavy in the second half of the season and even their performance will not be as good as before. But fortunately Napoli have collected a lot of points which certainly won't worry them.
But of course their allenatore, Spalletti, will face a tough task. He must be very smart in managing his team's strategy as well as how he must be observant in rotating players so that the players stay fit every week. if all of this can be done then it will be easier for Napoli to reach the Scudetto.
