The Napoli team is far ahead of these two teams, Juventus and Roma. Napoli's performance seems to be the same type of performance that the Juventus team has performed in the past. The Napoli team looks to be stronger next season judging by their current performances. And each player's style of play showed confidence.
Napoli really want to repeat their success again in the next season, it's clear because they keep their good players and don't sell them to any team even though they are interested in a high price. However, other big Italian teams such as Roma, Juventus, Milan and Inter have had good preparations to compete with Napoli in the following season, it seems that competition in Serie A will be fierce again.
i'm pretty sure it will be, Juventus and Inter Milan are two tough teams that i could see in top 3 next season, everyone will eb expecting Napoli to be good, and it could affect them in a negative way, their fans would have a high bar and things could go other ways with pressure and such.
