If we understand Napoli's condition better, it's not really a matter of adapting to Conte's strategy, but Napoli's slightly weak defensive performance and it's not certain whether it will last temporarily or whether it needs a change of players.
Although some people still believe that Napoli's defense is not bad, Napoli should have put up a fight against Verona or at least hold a draw.
We can see real evidence that conceding 3 goals is not something small, except 1-0, maybe that makes sense and indicates that Napoli's performance is quite good.
Indeed, this is only the beginning of the season, but we'll see later if they still perform badly against Bologna, I think there is something that needs to be fixed in Napoli's defense.
besides the problem in the defense line, I think the transition when attacking to defending that Napoli implemented was not successful. there was a delay in filling the gaps left when they tried to attack. while they also had problems in finishing.
Conte has a lot of work to do in the Napoli team. it will take time and will not happen in a short time. replacing some players may be a short-term solution, but the coordination of the game between players must be trained much longer.
