This season promises to be exciting and I say that because of how much improvements I have seen from sides like Roma and AC Milan but my support stays with Napoli, I think they have a better squad now than they had last season. If they could win the league title with the squad they had then I believe they can defend the title this season.
In the past two Serie A seasons the competition in Serie A was fierce, but with the involvement of Serie A clubs in the transfer window, I am expecting the upcoming Serie A season to be more fierce than the past two Serie A seasons because Serie A clubs have strengthened their teams, which will allow them to compete for the Scudetto next season. Napoli had a good squad last season, but with the addition of Kevin De Bruyne to their team, I see the reason why you chose to support Napoli to win the Scudetto next season.
Serie A has not had a champion who won it for 2 consecutive seasons for years, it shows how tight the competition in Serie A is in the hunt for the Scudetto and this season I also see teams like Juventus, Inter Milan and AC Milan trying to recruit good players to provide tight competition, so it is still too early to be confident in Napoli even though they added Kevin De Bruyne because as far as I know Kevin De Bruyne is not as strong as he used to be, but with teamwork with other players, Napoli can create a solid strength.
