Napoli will have to focus on the new season because this time, Napoli will have a more congested schedule. And perhaps their chances will be a little more difficult. Last season, Antonio Conte was able to focus his strategy solely on Serie A. However, this time, he will have to think twice because he also has to consider the stamina of his players to prevent fatigue amidst the heavier match schedule.
However, if Napoli remains more focused on Serie A, their chances will still be strong. But I doubt Napoli will focus solely on Serie A because I'm sure Napoli wants to carve their name as champions in the upcoming UCL. So, Napoli's goal is definitely glory in the upcoming UCL. But I doubt they will win the UCL. But I don't doubt them for Serie A.
It all depends on how he evaluates his strength in the Champions League. I think that in any case, he will want to defend the league title and win something again. Moreover, I believe he will have very good chances to do so, because considering the situation in other teams, Napoli looks relatively very strong. And in the Champions League, yes, I think every team would like to win that tournament, but if we evaluate things objectively, there are much stronger teams in Europe than Napoli, so I think the main focus will be on Serie A.
