I think Rudi can't perform well like Spalletti and Spalletti knew Napoli won't have a great season and earn achievement as they did in the last season.
In fact, one reason for Napoli to have this performance was the unstable situation of other teams and especially Inter Milan and Juventus otherwise they couldn't get these results and I think that's what we are going to see in the next season.
But that's not the case because Napoli last season was not only consistent in Serie A but also in the Champions League they were quite strong but they had to lose to Ac milan. Remembering Napoli journey in the previous season, we were all automatically surprised by Spalletti tactics that could make Napoli so consistent last season.
But Spalletti era with Napoli is over after he chose to resign due to a mismatch of vision and mission with the Napoli owner. So next season we will see Napoli coached by Rudi Carcia, where under his coaching will Napoli be able to progress consistently in Serie A or will they experience a different season next season.
I think the changes that have happened to Napoli will affect their performance next season. Especially Napoli success last season could not be separated from the slick performance of their coach Spalletti who was able to make changes in Napoli style of play last season. Even in this transfer window one of Napoli best defenders has left for Bayern Munich which will make Napoli lose a great player in the defensive area.
Even for Osimhen, speculation about his future is of course very much in question because he is the target of many big teams at the moment. So there is a high possibility that Osimhen will also go to another team in this transfer window. Apart from that, if some of Napoli core players leave for another team in this transfer market, it will definitely have a big impact on their decline in performance next season. I think Napoli should be wary of this in order to be able to keep the core players from staying with them next season.
