So far Napoli only lost vs Inter in the last 9 matches in all events. maybe is not more accurate when we look at some of them is a weak clubs, but we don't must heed there is inside team like Juventus and Roma, and in the champions league event also, they able to beat Frankfurt at home. so when meet Empoli, maybe is not hard to beat them with 2 goals, but sometime when team up on the wind, they sometime split make it draw.
The performance of Napoli makes me feel more about Juventus in seasons they dominated Serie A. Napoli even can play well in Champions League too and they got big advantage at the stadium of Frankfurt. With a home away win by two goal difference, Napoli will have to kill themselves to lose the ticket to quarter final of Champions League.
With their domination in the first leg, they will very possibly to repeat it in the second leg in Naples. Frankfurt won against Barcelona in Europa League past season and it was a big shock but in this season, Napoli will not allow them to create another shock.
I believe Napoli will get a win against Empoli, so far, Napoli's strength has increased and it has won five consecutive games, making Napoli even more confident about beating Empoli. The point gap between first and second place is 15 points, so there is no team trying to win first place, which is why the announcement of the Serie A victory is going to be accelerated.
Empoli is not a tough opponent for Napoli and they will try to collect as many points from weak opponents as possible. The point collection from weak opponents will help Napoli to officially take the trophy in Serie A. It will give them more time and resources to spend in Champions League. Napoli can make amazing Champions League adventure like Porto and Monaco in 2004 that is about 20 years ago.
