We still don't know the situation for the new season, but from what we've seen regarding transfers and team preparation, neither team is likely to see much change. On the other hand, Napoli looks set to be even stronger for the new season. They've made several transfers, and I'm sure they'll strengthen their performance. Napoli likely has bigger goals for the new season than just the Serie A trophy. They're certainly preparing for a major competition like the Champions League, which is very competitive.
Last season, Napoli failed to qualify for the Champions League, and this season they will once again represent Serie A in the most prestigious competition. And of course, Napoli and Antonio Conte won't waste this opportunity. As you mentioned, Napoli has big plans: to conquer Europe again.
The Champions League will certainly be a tough battle for Napoli, but their moves in the transfer market demonstrate their seriousness in preparing for the tougher competition. Meanwhile, in Serie A, I still believe they can perform well. The season hasn't even started yet, but I'm confident they can perform well in the new season . Rival teams may also improve their performances, but several teams are also going through transitions with managers and players coming and going.
