I think Rudi garcia is familiar with the atmosphere of Serie A because he has coached Rome before. I think a big challenge will come to him next season because Napoli's status is the reigning champion. With his coaching style, I'm sure he will be quickly understood by Napoli players. Well, one support for him is to keep his core players from leaving for other clubs in this season's transfer window, such as Osimhen and Kvaratskhelia.
Rudi Garcia had some good seasons with Roma but he did not help Roma to win Scudetto because Juventus dominated Serie A in 9 consecutive seasons. I believe he will not have too many difficulties when coming back to Serie A but protecting Scudetto is not easy for both Rudi Garcia and Napoli. We will have a clearer picture after an ending of the summer transfer season. If Napoli lose some key players, they will become weaker and have less chance to protect the crown.
Next season Napoli will be one of the teams that is highly reckoned with in Serie A after their good performances this season. Even next season Napoli will be quite busy with a busy schedule and I think Rudi garcia should understand this from now on where he has to buy better players to support himself in helping Napoli retain the title next season.
They will play in Serie A with more pressure as a champion and they will have to play in Champions League too. Success in the last season will cause more pressure on Napoli in a new season. It together with challenge to adapt to tactics of a new coach, will result in a chaotic season for them.
Oh yes, after such a successful last season, Napoli will need to try hard to repeat this success again. I'm not sure that even Luciano Spalletti, who can be called the father of this great success, could have done it, and what can we say about Rudy Garcia. Well, I wish him success, but I doubt it very much.
I believe that Napoli won't be able to protect their Scudetto and go to farther than Champions League quarter final. The new season will be successful for Napoli if they complete it in top four and reach to quarter finals like the past season.
