It can be said that the change of coach will determine the percentage of success for next season, in addition to the entry and exit of players. The surprises haven't ended as long as the transfer market hasn't closed, anything can still happen and not only Napoli. At least the most realistic target is to finish in the Champions League Zone next season, because it is profitable in terms of income and players will stay at the club. Juventus, AC Milan, Inter Milan, AS Roma and Napoli are the most favorite clubs.
What's interesting to look forward to is luck on AS Roma side, Jose Mourinho hasn't won the Scudetto since coaching the Capital club, becoming a motivation for him as a strong contender for next season.
Sometimes the change in the managerial role in a club really affects the team negatively because players find it difficult to adapt and understand the tactics of the new manager, just like the situation that happened when the ownership of Chelsea was changed and the new owner had to replace their manager with a new coach with potential but it turned out very bad because his style of play and was too hard for the player to adapt to.
Napoli had a very successful season and were regarded as one of the toughest team in the world but there's going to be a big doubt over whether they would be able to replicate the success rate of last season and perform better than they did to be able to defend their trophy this season, the good thing for them is that majority of the players they had last season are still intact and their new manager Rudi Garcia have had experience in the Italian league coaching AS Roma even though he's not had a trophy in is coaching career. Napoli is going to face a very big competition from Juventus and intermilan mostly and next season would be very tough because Juve would want to get back to the top as champions of Italy.
