Milan which currently follows under Napoli, will face Salernitana and Roma in the next two matches. If look at the level of difficulty with the opponents that Napoli will face, Milan has the potential to get full points and get closer to Napoli in the standings.
Napoli needs to be careful with Juventus and Inter. They have been in good form recently, Especially Juventus, who are unbeaten in the last five matches.
Napoli have a slightly more difficult opponent in the next few matches after the World Cup compared to AC Milan, Perhaps Milan's toughest opponent, namely AS Roma and previously against Salernita, was an easy match for Milan to gain maximum points. Unlike Napoli, who had to face Inter Milan and Juventus, both teams are currently in pretty good form. Moreover, Juventus' performance, which won 6 recently wins in Serie A, made Napoli have to perform optimally if they wanted to get 3 points.
But Napoli have more enough points left with Milan on standing position, seems difficult opponent with Juventus and Inter although without any point achievement yet, Napoli still lead standing position behind Milan.
They will still be playing against another top team anyway, so I don't think there is anything to lose or gain. But indeed, when the matchday is held at the weekend and in the middle of the week they play in the Champions League and/or also in the European League then of course, such a schedule will prevent them from getting the maximum rotation of players.
But if I consider that at least they still have a chance to win against each other, because over time their performance will certainly change.
Therefore, Napoli will indeed be more demanded to win, but at the same time Napoli must also be able to focus on the Champions League.
For a team like Napoli this might be a very good season for them, but it will also be a very tough season if Napoli are targeting good results in two different competitions.
