If Spaletti does leave Napoli, it would probably be a tragedy for the club. With him, Napoli have been able to achieve very good results that could disappear next season. There are so many examples of a top club ending up in the middle of the standings after a coach leaves. For example, this was the case recently with Barcelona, who were only able to recover after a season.
It is inconceivable what will be the fate of Napoli after Spalletti left, maybe his fate will be the same as Brighton after Potter moved to Chelsea some time ago. Napoli have achieved success with Spalletti, the coach really played a big part in helping Napoli win the Scudetto after not having won it for a long time due to not being able to compete with Juventus, Milan and Inter.
Chaos will befall the Napoli squad if they can't convince Spalletti to stay, the new coach's ideology makes players have to adapt to the style of play that is applied. The success of a club is not only equipped with an established squad, but the role of the coach is also very important in determining the right strategy.
