Napoli played a great game and demonstrated it on the field of being the best team, or at least one of the best, played a clean football, I had predicted a draw but the Neapolitans immediately denied me they made their players assert better and this is not easy, Lukaku has totally dominated the game, for the next challenges they will surely be more fit and more concentrated after such a victory
Yes, that was a lovely performance by Napoli in the 2nd half. They didn't start well but made up for it shortly. Juventus finally got their 1st loss of the season in the Serie A. Some fans started to go harsher on Motta after this result. They were already criticizing him because of not being able to win matches. I feel like it wouldn't be the right thing to ask him to get sacked this quick. I believe Juventus need transfers to get more productive. I don't think it is because of Motta for now.
This team has been in need of some reinforcement for a long time. Allegri wasn't given enough money. But maybe Motta can be given. Then we would find out how good he will do after adding new players.

No matter how good the defense is to maintain the score advantage, in the end their defense can concede. This is clearly a serious consideration for me, because I also saw Juventus play several times even though they only played against mediocre teams, but Juventus really did not have the morale to continue to make strong attacks when they had the lead. So, very often Juventus concede and end the result with a draw and thus also, then playing against Napoli, Juventus should continue to attack and pressure instead of making a full defense in the second half.
Thus, Napoli were free to continue to attack until in fact, Napoli managed to turn things around and make Juventus get their first defeat this season. With these results, it is appropriate for Motta to change his tactics and strategies, because a team will not be able to be in the best position in the standings if the results only get more frequent draws.
