I don't know why Luciano Spalletti will just turn his back on Napoli when the star is shining brighter, I guess the guy did not believe in the second time of a good performance like this season, so, he stylishly exited. As for Rudi Garcia, I don't know much about the guy but I believe him as an old player and coach that he would be able to deliver in his own little way. I will not cast much doubt in a good performance of Napoli in the next season, but that is only if they do not eventually sell Victor Osimhen.
Maybe he just wants to take a break? Isn't that normal amongst managers too. We have seen lot of managers taking a break and its understandable with the way they have managed such top teams competing in lot of competitions so lot of pressure is there when it comes to managing. I don't think its "turning back" on Napoli as Spalletti left Napoli and just simply taking a break. However, it would have been different if he left and went on to manage a rival of Napoli in Serie A but that's not the case here.
