It must be such a delightful win against Juventus for Napoli fans.

Because they beat a team that didn't lose a single time in 21 league games. It sounds easy when you say it but it was a really impressive record for Juventus.
When Juventus got ahead first, I was like "No way!". But there was a completely different Napoli in the second half. It seems like Conte played his best card to fire up the players.

Good thing he did there though...
Juventus couldn't do anything in the second half at the same time. They were so ineffective that they only focused on keeping the score at the same level. But at least I would expect them to react to the equalizer.

In fact, it’s even a bit of a shame that Juventus’ absurd (too many draws and zero losses) streak has been interrupted. But the good news is that Napoli did it. At one point it seemed that Napoli had slowed down and Inter would easily dominate (and therefore there would be no intrigue) but Napoli got back into the game and are now on equal terms with Inter.
