Napoli was lucky last season that the competition wasn't as fierce as this, they wouldn't have lifted up the trophy. It's possible that Napoli will sink below the second possition if they don't stay strong for so long. I was expecting that they should have played draw since Milan was on shut one. Assuming, Milan didn't commit that foul led to a red card and a penalty, Milan would have beaten them on clean sheet.
Should we really count Napoli lucky from last season? How about the fact that they did pit in some good efforts last season, I understand that at some point, not all of the efforts were as much but some sort of work was put into activities actions. They had Inter and others who did compete tough last season, so far this season has not even been as tough, by this time last season Napoli was not top three and so it was not believed they will win eventually so this season I believe is yet to be as tough.
