Juventus often look better when they appear in front of their fans, which is why home games give them a lot of points, it's just that this season Juventus has become a team that has difficulty scoring many goals so we can see several times they won with only a score of 1-0.
Vlahovic has a bad season and it's big change from what he performed in previous seasons with Fiorentina and even in the second half of last season. The injury of some players like F. Chiesa, Pogba impacted their attacking system too.
Napoli this season has been the most productive team with an average goal per game of 2, so it is very possible that Juve's defenders will find it difficult to keep their goal safe if they apply a defensive strategy that they often do in many matches, and if Napoli's main striker is fit and playing full will make Napoli's attack even more dangerous, but I think any result can happen, and making it to the semi-finals of the champions league and also winning an appeal will give extra motivation for Juve's players so they can be different tomorrow.
Napoli will play aggressively to find a win and forget about their failure in Champions League. They can beat Juventus and take it an own gift to forget Champions League defeat days ago. It will help Napoli to come closer to Scudetto which mostly belongs to them.
Juventus just have a big change in this week, from no hope to participate in top four to jump directly to a third position. At least they are in a safe place now but they must play well to keep up their position because there are AS Roma, AC Milan and Inter Milan are wanting to join top four and differences are not big among those clubs.
