Juventus still haven't lost in the league. Napoli away game will be tough for Juventus. However, Juventus has a structure that doesn't give up on fighting against every team. They have young and good players and Motta seems to have taught the team the best way to defend. They played against strong opponents in the Italian League but they still haven't lost. We can say the same thing for Napoli. Maybe they won't lose against Napoli either but I think Juventus will be the closest to losing.
I am very disappointed with Juventus' performance this season. Juventus players probably have a main target in every match to draw. Juventus have drawn 13 out of 21 matches. Juventus have drawn 3 out of 7 matches on the Champions League platform. I would say that Juventus team is in a very bad form.
Napoli is very strong this season. The top spot of the points table is occupied by Napoli. Napoli will have a target to win against Juventus as well. However, breaking Juventus' defense will definitely be difficult for Napoli. Napoli coach Antonio CONTE will definitely have to try to find the weaknesses of Juventus' defense. I am sure Juventus will play defensively in this match as well and try to draw the match.
