You're right the year that napoli won the scudetto they where not in the champions League and the after qualifying for the champions League they find it difficult to cop with so this coming season Napoli should look for a way to rotate their team so that fatigue will not set in and affect the general performance of the team because this coming season will be more challenging
Napoli seems to be the finishing end when they lost almost all their key players and also their manager. What was the plan of Napoli after their terrific years to win trophies? The Seria A was essential for Napoli and they came out prepared and ready to lift the trophy. This was their prime form, flogged oppositions with huge goals margins but not seeing anything this period, then I asked myself what's going on with the club. They just have to bounce back because it was an important moves, knowing the styles and innovative changes that follows, Napoli will gather more strength and bringing in tactical changes.
Napoli's success in winning the Scudetto last season can be a reference for them to build a better team, actually this team is in the process with Conte but surprisingly in the first season they were immediately able to win the Scudetto so the same thing is possible to happen next season even though it will not be easy especially Napoli must share focus on the Champions League competition but in my opinion it is not a big problem if there is no storm of injuries coming in this team and Conte can strengthen players in all lines to maintain the stability of the team I think they can be better next season.
