Napoli team is performing well this season. The coaching staff of the team has worked brilliantly for the development of the team. The result of which we can see in the matches. As they are performing well compared to last season, expect better things in this season.
This is different from last season, we can't see what they did last season but we have to be realistic in looking at this season as a whole not only in UCL matches but in the domestic league too.
Napoli are currently in a very bad state, plus recently there has been news that there is no longer a harmonious relationship with their mainstay forward, Victor Osimhen, which could possibly make this team even worse if chaos occurs within this team.
If we look so far and if the Napoli team can't recover then I don't think they will be able to do it again like what they did last season.
