Napoli took the right decision by bringing in Antonio Conte, a coach who is very experienced in the Italian Serie A. He will be Napoli's head coach next season Of course, with the arrival of Antonio Conte, Napoli hopes to be successful again next season, but if they don't spend any money just obey the players that Antonio Conte wants, this is a loss.
The reason is, Napoli's players this season are very minimal in all fields, therefore new player formations must be available to be able to return to an era of success.
I think if Antonio Conte is able to train well with the players who are already at Napoli, it would not be wrong for Napoli not to bring in other new players into their squad next season. However, if Napoli had more money for this, it would be much better because a coach like Antonio Conte would also consider improving Napoli's performance next season. Because Napoli needs to show its best performance again next season after having slumped a bit this season in Serie A.
