About Roma, I agree with you. They didn't do well in Serie A, but they played in the Europa League final. This is already a good result for them. I don't agree about Inter. They did very well in Serie A and played in the Champions League final no worse than Manchester City. It's just that Napoli didn't give anyone a chance in Italy this season, so it seems that the other clubs played badly.
this season in Serie A maybe only Napoli are playing consistently. whereas other strong teams such as Juventus, Inter, Milan, and Roma tend to play inconsistently. we cannot guarantee Napoli's game will be the same this season as last season. what is clear is that there are several players who have come and also moved into the transfer market this summer. so we can't measure the strength of each team last season. what is clear is that this season we definitely want to see how Serie A becomes even more competitive with solid teams.
Last season Napoli showed from the start of the season that they would be the leaders because they didn't lose 15 games in a row. Even then it was clear that the other clubs would not be able to get to the top. Of course, next season everything should change after the leave of a key player and the change of the coach. The competition will probably be high.
