Napoli players played very well and they won. Their performance was very organized. But I wouldn't say they dominated the match. 61% ball possession in this match. And Fiorentina players attacked more than Napoli players. Fiorentina players were able to make 16 shots. On the other hand, Napoli players made 8 shots. However, Napoli's gameplay was very organized. They kept their defense strong and then continued to attack. And every Napoli attack was very planned. Napoli's overall performance was very good. They got an excellent 3-0 win.
The Napoli team's play was quite effective so they managed to score 3 goals even though overall they didn't create more chances, this was quite an important victory for Napoli.
However, on the other hand, I feel that Fiorentina's performance was really bad enough in this match (unlike usual) so that Napoli was able to win with a fairly big score.
Napoli did win the match but I don't think that their quality has improved and are better, I still think that Napoli has a lot to improve, this victory cannot be separated from Fiorentina's underperformance.
