It's hard to being an unbeatable in whole matches of season and during Serie A history only Juventus and AC Milan who able became the champion of this competition with unbeatable status but at that time these teams weren't gets strong contender which mean they are too strong at that time but Serie A currently was different even more competitive than previously because some of mediocre teams can possibly makes big teams slipped and in my opinion Napoli probably will lose once or two times this season but i think they can able to maintain their performance until at the end of this season so Serie A title almost certainly will belongs to them
Napoli's focus only has to be a champion regardless of defeat or not. I don't think it really matters too much, the most important thing is that Napoli win.
It's been too long since Napoli had to lose and last lost when they won 3 decades ago and at best they were only in position 2. Now is the right time for them to be able to bring back a trophy with a very big chance. Regardless of losing a few times or not later it doesn't matter, the important thing is they can continue to stay in the top position now.
Im not a Napoli fan but i feel always felt sad about this club because they always did great seasons but without any trophy, the club now have a golden chance to finally get a trophy and why not start a golden edge full of trophies for Napoli
