Last season, Napoli managed to show their strength in matches in the Serie A League and were in first place at the top of the standings. At least Spalletti has very good experience at Napoli, while Rugi Garcia is still relatively new, and I doubt whether Napoli will dominate the Serie A next season or not.Usually, a change of coach becomes one of the triggers for winning or losing and becomes part of the journey of a soccer club.
We can't jump to conclusions and doubt him just because he's a newcomer we should at least give him a chance at least until mid-season
Rudi Garcia already has experience in several leagues his abilities can be applied in any team including Napoli I have no doubt about that
Moreover, Napoli still uses the same team composition so Rudi Garcia just needs to continue domination and strategy.
