Yes, Napoli will be the best Candidate for serie A because their players are well organized in this season to work together to ensure they keep the victory going until they stand for final to prove to the whole world that they are the best for the tournament
They are the best now but in future, at the end of season, I don't know. They might make us disappointed again as they did in some past seasons. This season, they are not competing with dominating club like Juventus years ago. But they are in a similar season like the past one, they even have more competitors in this season, not only Inter Milan and AC Milan.
If Napoli strikers can maintain this strategies they are using in this season, I think they will defeat any strong teams in this Italian league competition to embrace the title
Their attacking players are doing good but to win Serie A and take Scudetto, they need strong defense too. It is surprise to see Napoli destroyed Ajax in Champions League too. It means their whole system especially attacking system is very good at the moment.
