I don't expect to see big changes happening for Napoli due to the reason I mentioned. They are even likely to keep their most important players in the squad for now as well. This should be enough to keep them in the title race in the Serie A again.
They will only be in the title race but I doubt they (Napoli) can do as much as they did last season, especially their manager is not Spalletti anymore. There will be a lot of changes going on there later, I just hope they're not the same as Chelsea in the EPL who are a big team that has slumped. If that happens, of course people will be confused by the setback they are experiencing.
