If Luciano Spalleti had been retained, persuaded further to stay as the club's head coach, I would have been completely confident in the club's capacity to maintain consistent winning outcomes. We have yet to see how the new boss will manage the Parthenopeans, but we can always hope for the best from everyone, including the new boss, the players, and the supporters. Napoli is an exceptional club in the Italian league, with exceptional performance. There is no reason to be concerned about the club's performance next season; they will, without a doubt, keep their top-tier status in Seria A.
It is no longer possible for Luciano Spalletti to survive, he has already announced his retirement from coaching Napoli on the grounds that he will take time off and rest for a period of one year. He will not be coaching another club next season and will be completely resting for the time being. Rumors circulated that Spalletti had an argument with the club president and there was no further explanation about the cause, perhaps this was a factor for Spalletti to temporarily stop.
Napoli have shown a new coach Rudi Garcia for next season to replace Spalletti, I think this will not be much different and will have an impact on the club's performance for next season. considering that the Napoli squad is still the same as last season, my prediction is that Napoli will experience a decline in performance as a team if they actually release their flagship striker Osimhen.
