Sure thing! I totally agree with you that Napoli is on a roll and they're likely to keep winning, even though anything can happen in football. I mean, Sassuolo beating Napoli would be crazier than me winning a gold medal in figure skating, and trust me, I'm no Tonya Harding. But seriously, Napoli is on fire right now and playing some of the best football of the season. It's gonna be a great game against Sassuolo, and I'm excited to see what happens. Go Napoli!
It's okay to remain optimistic about Napoli's winning streak in Serie A, I think they are safe even if they have to lose one or two games remaining this season. Sassuolo are not weak team, they can surprise anyone including Napoli if they make mistake. The chance are best that Napoli win, while the other two have low probabilities including draw or Sassuolo win.
Sassuolo is also unbeaten in their last 4 matches in Serie A, so it's not only Napoli who has a good performance even if the home team doesn't win everything. Napoli lead in quality, while Sassuolo must know how to handle it.
