It is normal for a new coach like Antonio Conte to give new enthusiasm and new hope to Napoli who want to win again. You need to know that everything Antonio Conte says cannot give a guarantee that Napoli can win again in the coming season. I'd rather have a lot of action than have a lot of crap like that. Antonio Conte only needs to provide enthusiasm and understand the players' skills in order to find the right strategy to achieve victory in every match he faces.
Yes, it is normal, Antonio Conte is one of the successful coach from Italy. Antonio Conte won 3 Serie A trophy with Juventus and 1 Serie A trophy with Inter Milan. His ability is proven already in Serie A, so it makes sense if Napoli president is very optimistic with Antonio Conte. Sure, there is no guarantee that Antonio Conte will automatically win the scudetto (Serie A title/trophy) in the next season. However, I'm sure Napoli will be a better team under Conte's management. He is one of the coaches who has a good characteristic and has a nice relationship among the players. I hope he can ensure Osimhen and Kvaratskhelia to stay in the club. He must plan to buy some top players to support Osimhen and Kvaratskhelia, and must strengthen Napoli again.
It seems difficult for Inter Milan to achieve the achievements that Juventus has done in dominating the Serie A title because in my opinion, in terms of DNA, the champion most likely to be able to match Juventus' achievements is AC Milan. But the problem is that AC Milan's performance in the last few seasons has been unstable. However, I am sure that next season the competition for the Serie A title will definitely be even tighter.
Inter Milan also has a championship DNA. With the current squad of Inter Milan, I no doubt that they will be able to defense their champion status in the next season. Moreover, the performance of Juventus, AC Milan, Napoli, and AS Roma are very unstable now. Those teams also have not really good squad. Among the top teams in Serie A, I think Inter Milan has the strongest squad. I assume the champion will be still Inter Milan, but maybe it won't be as easy as in the season 2023-2024.
