Next season it is very likely that there will be a difference in terms of title competition in Serie A, but Napoli will also try their best strategy to be able to get several wins since the start of the season even though the coach is different for next season. But each coach will also study and see how the previous Napoli team performed so that they can apply the things that Napoli previously needed next season. But I'm also sure that the competition will be very different next season and it won't be easy for anyone.
Serie A is quite random lately, you never know the team that will lift the scudetto. Napoli until now are one of the best since they are holding their best players. Inter, Milan, Roma didn't made a lot of changes while Juventus are still in progress. We have to wait until the end of this summer transfer window to know how every team looks like and their ability to fight for the top spots.
