Napoli will continue to keep their lead even if Milan equalize the points this week. But I don't even wait for Napoli to lose points against Sassuolo.
Sassuolo aren't having a very good season. They don't seem durable enough to fight back hard against this in-form Napoli. Napoli are literally dominating the season without a loss yet. I think they will get another win in this and move on.
Playing at home, it is certain that Napoli can secure three points, and still hold an unbeaten record until week 12, Napoli's performance is very promising, they play very consistently, even in the Champions League they were able to become the top of the standings and beat Liverpool. Napoli's appearance is very different from last season, I hope Napoli will continue to play consistently until the end of the season.
