I also really hope for a much greater level of competition in Serie A this season because it will provide quite an interesting spectacle for all circles who like the Italian League. Even before this season started, Napoli was doubted to perform well in Serie A, but in reality what we see now is very different where Napoli was able to bring itself to the top of the standings after six matches at the start of this season. And on the one hand I also think that it could be because of Conte's influence who is coaching Napoli this season, but considering that the season is still very long, of course Conte still has the task of making Napoli more consistent in winning every match in Serie A this season.
If they can get past Napoli then they will be tested as you have said that Napoli have won a lot of matches and are in a good position at the moment. If Conte hasn't done anything in such a long time, who will stop Napoli later on? Yes, there are many matches now, but they have less time because any team in the league can win at any time and lose at any time. I don't expect Conte to stop Napoli. Yes, but there are other strong teams in this league, so they can stop Napoli. They want to prove themselves to be the best in this league and some will doubt it. Because for some people it's an underdog team and as you mentioned they've just performed and are going up as the season starts. Now such teams will change the direction of the game that even Conte will wonder which way the game is going. But Napoli has become a strong team at the moment, after some time or few matches they will also become weak.
Conte has enough experience in Italy, he has been successful as a player and coach. Conte's presence is certainly a challenge for other coaches, especially those who coach big teams like Simone Inzaghi who was successful with Inter Milan. Napoli has been able to appear solid so far, but there is no guarantee that they will be able to run smoothly. I am sure that in the second round there will be several teams trying to improve their current squad so that they have the opportunity to make a more serious challenge to the favored team like Napoli.
