I hope that napoli's performance will be recovering again. I don't wanna see that napoli will get lose streak once napoli one step closed to the scudetto caused by napoli was able making very big gaps to the second position. Napoli must also think about how to be consistent again. Spalletti has a lot of home work to make sure napoli will not be approached by another team. Napoli has so many advantage over another team like ac milan. I hope that napoli can use the golden opportunity to make the gap even bigger. Losing 4-1 against LOSC was a big shame for napoli
Friendly match result is not really important trough Napoli squat not completed yet with several player not back from their national team after World Cup, honestly two friendly matches loss from Villareal and Lille can't make Napoli have underperformance in Serie A begin two weeks later.
Serie A will start two weeks later or January 5 and Napoli still have enough time how recovering and back to top performance, actually I don't think bad achievement in friendly matches have bad impact for Napoli in Serie A after having consistency performance from 15 matches.
From all Serie A participants team, Napoli become the only one team still unbeaten.
