For Juventus, winning Seria A would be difficult, they might have got a good defense to keep them going but not the attackers who have seen one of the lowest goals scored. Just like they've both done in the past I believe this is a game that Juventus would still win. The transfer window fast approaching they should bring in players to replace Paul Pogba and sign a quality winger or striker to help score goals for the club then, we can talk of them winning the Seria A league tittle.
I agree with you the only lack of Juventus is the attacker Juventus only scored 22 goals in 14 matches or the lowest when compared to 5 other competitors of course this achievement is unreliable if they want to compete for the title therefore I agree that Juventus must move in the upcoming transfer window, their main focus is the attack line to increase goal activity. Inter Milan will be the main competitor for Juventus both teams have played well so far it's just that Inter Milan are better in defense and attack somehow Juventus can pursue them.
Napoli will face Juventus today and I am not sure Napoli can beat Juventus the best opportunity for Napoli is to draw while they need points to be able to go up to 4th place or Roma will stay there, I saw Napoli like Tottenham who slowly continued to decline in performance and they continue to lose important points. Do you think Napoli can get 1 or 3 points today?
Juventus' goal productivity is mediocre and indeed the lowest compared to the other big 5, but Juventus doesn't concede many goals. Juventus' defense is quite strong. It seems that Juventus prioritizes their defense more than goal productivity, but I think Allegri has to think about this apart from keeping Juventus' defense strong. Juventus also needs to increase goal productivity so that it can be like other rivals at the top.
This match is very important for Juventus for continues to be a big pressure for Inter, but you need to remember that Napoli is not an easy opponent but Napoli is unstable. Juventus can definitely make good use of this match, especially since Juventus will play at home Juventus strength is almost equal to Inter, but It seems like Juventus didn't score as many goals as Inter did when they won the match against Napoli a few days ago.
