Pre- season games or club friendlies isn't a criterion to judge a team as to how it will performs during the main league open competition, sometimes may take or don't take those matches that seriously because there is no cup tied it, I have seen a situation where a team that did well during their pre-season games and when the league commenced, we became amazed with how they were struggling to win their matches
Indeed, not all clubs will bring out their optimal and serious abilities in matches like this pre-season. Especially big clubs, usually will be more focused on testing the movements of all the squads they bring and not all main squads will enter. Then, not all clubs will also act very stubbornly to win the match, because it is feared that injuries will occur. This is just a pre-season match, in general it may not be too noticed or considered as the progress or decline of a club. only, maybe specifically for their coach, it becomes one of the trials and assessments of each individual in the training session in the pre-season match.
Napoli are still busy in this transfer market so we haven't seen the real strength that Napoli has. Yes, Serie A is almost underway with 19 days left until the first match will start. For this reason, Napoli must prepare their new strength by recruiting several players in the transfer market, especially for the defense line which they must improve because last season Napoli's defense was so fragile.
They are still quite active in the transfer market. Indeed, at least the rumor that is currently attached to them is related to the Osimhen - Lukaku rumor, which is unknown until it will really end, and how it will end. As for the next rumor, Napoli's interest in Billy Gilmour, Brighton's Defensive Midfield who is currently 23 years old. However, basically, the clubs in Serie A are still quite active in the transfer market.
Apart from Napoli, which is currently quite heavily rumored to be eyeing on some players is Juventus. Where, Juventus is also rumored to be in negotiations for several players they are targeting. Some of them are Teun Koopmeiners, Attacking Midfield Atalanta. Juventus has offered their first bid of 45 million euros. However, the news is that Atalanta rejected that bid, and they rejected Juventus' efforts to get Koopmeiners.
