Luciano Spalletti's current age is indeed in the retirement age area. Namely, at this time Luciano Spalletti is already 64 years old. So it is very natural for Spalletti to decide to take a break from his profession as a coach. But Spalletti seems like he just wants to rest for a while. And maybe he will return to coach for other teams interested in him.
Regarding Napoli, it seems that they have targeted several new coach candidates to replace Spalletti. In fact, one of them who was mentioned as one of the candidates to become Napoli coach is Antonio Conte, whose name is already familiar to Premier League fans. well Conte is a former Tottenham coach who was sacked in March. and at the moment it seems that Antonio conte's status is still free.
One thing that has stolen enough attention is his skill in building Napoli this season which will always be remembered by the fans for the seasons to come. Apart from that, one of the things that allows him to take a break for a while is the aging factor because he is already 64 years old. Now this situation really shocked the public, even I think the Napoli players were also surprised to hear this. But will they also take the attitude to leave in the upcoming transfer window considering that Osimhen and kvaratskhelia are the players who really steal the attention of big clubs in the transfer window next summer.
So, if several players leave in the upcoming transfer window, it will automatically make it difficult for Napoli to compete next season. Apart from that, I hope that this situation that occurs does not cause a big problem for all the players, especially their star players.
There are at least 2 core players who have been rumored to be leaving Napoli, namely Osimhen and Kim Min Jae. But I think the Napoli side will probably try to keep Osimhen at all costs. An offer of a raise might be one of them. And about Kim Min Jae, it has also been reported that he is the target of two Premier League clubs, namely Newcastle and Manchester United. But this is still just a rumor so there is no confirmation of the truth of the rumor. And like you said, thats true about the point is if the great players from Napoli also leave then of course Napoli will have a little trouble in the coming season.
