Well, although Juventus are still unbeaten so far, that doesn't mean Juventus will be able to beat Napoli in the next Serie A match. Moreover, Juventus will also be playing away and I think Juventus will only focus on getting another draw. But unfortunately, it looks like it will be difficult for Juventus not to concede because after all, Napoli still has consistent results with its current winning streak. Indeed, Juventus also managed to beat Milan with a score of 2-0 in the previous match, but Napoli are a different team and also, Napoli managed to beat Atalanta in the previous away match. At least these results are enough to provide a reference also that Napoli are still better under Conte this season, so I believe Napoli will have a good chance to win.
Juventus still have some sort of advantage going into this game and shouldn't be considered the underdogs in this game because they haven't lost in the serie A this season and are still unbeaten which means it wouldn't be just easy for Napoli to override Juventus even with the home advantage but Napoli would pressurise them no doubt because they are league leaders and would strife to extend their lead at the top if possible. So for me, I think it would be a game of chance for both teams, whichever side can take the lead first stands a good chance of winning the match.
If you realize and pay attention every time Juventus plays, the fact is Juventus more often managed to make a goal first, but for the final result is a draw. Therefore, earlier I said Juventus will probably only focus on a draw, because Juventus really don't have the ability to maintain a score advantage so far. Indeed, previously Juventus managed to beat Milan, but Milan has a new coach, although Milan managed to get the Super Cup trophy, but Milan with its new coach still needs time to adapt.
But about Napoli under Conte, they have had good results since the beginning of the season, so I said before Napoli is a different team at this moment. Although indeed, I also still recognize Juventus has a chance to win, but it will certainly be difficult to happen considering Juventus is only more focused on a draw. Even if for example Juventus manages to score first, there is still no guarantee that Juventus will be able to maintain it.
That not withstanding, I believe also that you might have noticed that Juventus have been able to handle the big teams more effectively this season despite not having much wins in the league which shows how proactively they have been despite not having a great campaign this season. Juventus have probably lost to only one of the big side Milan, a game which wasn't in the league but a Cup match. And having draws doesn't make them worse although it doesn't reflect their standard. I think this stats would be an added advantage for them when they face Napoli this weekend.
