I think Napoli have been unlucky so far. This is what is difficult for every club to implement, maintaining last season's top position will always be difficult because the team's weak points are not addressed and largely because Napoli have lost several important factors this is surprising. Indeed, in the match against Bologna, they could dominate but they just need a little luck and be more clinical in taking advantage of their opportunities.
Why they are unlucky? They actually still have enough top players. They just can't optimize their performance because they have new tactics/strategies. Now, with a new coach (Rudi Garcia), Napoli applies a different game style. Under a new coach, Napoli players' mentality seems not as well as in the previous season. That's why Napoli turns to be like a different team this season.
IMO, Napoli doesn't need to maintain the top position as the last season. But they should be in the top 4 (UCL zone) at least. And Napoli shouldn't get difficulty against small teams like Bologna and Genoa. We know that Napoli still has Osimhen, Kvaratskhelia, Zielinski, and Rrahmani. With these players, Napoli should play better than the 2 last matches in Serie A.
However, when a club changes coaches then of course there will definitely be changes within the club. Even though it's still the same players. But with a different coach it will definitely still make things different. That's what happened in Naples.
However, the most striking difference from Napoli is Osimhen's performance which has decreased. Osimhen's skills in swiping and running are still the same. But Osimhen's shooting accuracy doesn't seem as sharp as last season. I see Osimhen missing too many opportunities.
But I still hope that Napoli can restore their confidence and return to their best performance.
Today Napoli will face Udinese. And the history of meetings between the two always shows positive results for Napoli. Udinese have not won once against Napoli in the last 5 meetings. And now Udinese must come to Napoli's home ground. So Napoli should be the favorite here. Maybe we have to see whether in this match Napoli can restore their confidence or not.
