Sassuolo, Pisa, and Cremonese are the three promoted teams, but only Sassuolo failed to earn points. Meanwhile, Cremonese's results surprised everyone. However, I can't predict how consistent they will be over the course of the season. For the promoted teams, I think it's a good thing if they can survive for a second season. This is based on player statistics and the transfers they've made. Currently, I still see that teams with better players and more money tend to be more successful in staying in Serie A.
Some newly promoted teams sometimes perform beyond expectations. For example, Como did last season. And this season, there might be others. But Pisa were fortunate to hold Atalanta to a draw. And Cremonese were excellent, beating AC Milan.
I think Sassuolo were unlucky to face Napoli in their opening match, which cost them points. An important note from the start of this season, in my opinion, is that Inter Milan cannot be underestimated. I thought they would be poor this season. And I had more hope for AC Milan. But now it seems Inter Milan can be expected to maintain their solid strength. And AC Milan hasn't performed as well as expected. Napoli, AS Roma, Juventus, Como, and Inter Milan have all played well. And Atalanta looks set for a poor season.
