For next week, Napoli will face another big team. This is like a disaster that keeps happening to Napoli in a row. After losing to Ral Madrid, then Inter, and then having to play Juventus next week. This will definitely have an impact on their mentality. And this will be a very big challenge for Mazarri.
I agree that Juventus is likely to beat Napoli because they will play at home and they are in a good performance this season. It is very different with Napoli which looks very unstable although they already signed a new coach. In the last match, Inter Milan defeated them with 3 goals, it clearly showed that Napoli isn't in a good condition. Since Juventus strength is almost similar with Inter, they are also possible to beat Napoli with 2 goals at least. I don't see a chance for Napoli to get points in Juventus home. It probably will be the next defeat for them.
Exatly, Juventus will definitely try optimally, especially because they are competing at home. So there is also an opportunity for them to prove that this season, Juventus is really worthy of being taken into account. They had serious problems last season, and this season they will really go all out in fighting for the Serie A title. Napoli is a big club, but their code is not good at the moment. So Juventus' opportunity is quite big.
