Napoli have fallen far behind so it will probably not be possible for them to get back into a good position again this time. The way Inter are playing makes it much easier for them to become champions. Inter are ahead of the other teams on points, so it will be very challenging for the other teams to overtake them. Napoli didn't focus on their performance early on which is why they are in the situation they are now. So I can't consider Napoli as likely to do anything good ever
Now Napoli is also starting to be chased by other teams such as Fiorentina after the Fiorentina team won in their home match today and Napoli's own number of points is also the same as Fiorentina. So Napoli are now really feeling the pressure to maintain their position in the top four of the standings and must be able to do something to stay in that position during this season. Because this season it will be very difficult for Napoli to get a trophy like they got last season, but at least Napoli can get a top four position so they can enter the UCL competition again next season.
Also, Napoli current position is still being targeted by Roma and Bologna, which is 2 points different. If Bologna or Roma get three points in today match then Napoli position will drop to 5th place. But the Bologna vs Roma match also is unpredictable, both of team at the same level and I think there's still a possibility this match will end in a draw result.
Yes Napoli situation in the standings is full of pressure, but also Napoli performance seems already improve after Mazzarri leadership as head coach, and I hope they can back their good trend in every match to get a UCL ticket.
