At least 5-6 players of Juventus are injured and these players, who are in the most important roles of the team, I am surprised how they resist so well in the absence of these players, I really need to be congratulated. For the Napoli match that will be played tomorrow, if Napoli gets three points from this match, in my opinion, this point gap will be widened, even an early sign of the championship. The probability of the match ending in a draw seems high to me.
You are right, some key players of Juventus are injured (Vlahovic, Cuadrado, Pogba, Bonucci, De Sciglio). It is great that Juventus can win in each match without them, the substitution players showed that they have good quality, too. However, it seems hard to play against Napoli with too many injured players. Napoli is the strongest team in Serie A this season, they also have no injured players. So, Napoli will play with their full team. If Juventus can't play with their most key players, I also doubt Juventus to get points. Well, as you said, it seems Napoli to get 3 points and they will maintain their position at the top table. Juventus needs a miracle to get a point in this match.
