Guys Napoli is a strong team but not from today.
He's been playing at very high levels for years, I hope you didn't wake up today to discover Napoli.
After years of playing at very high quality levels obviously the team has strengthened and gained confidence in their way of playing and obviously it works like a perfect clock.
Spalletti is also really good.
I expect this to happen with Roma too, he's been playing very well for years, then he took on Mourinho as coach who fixed some things and allowed Roma to win the cup.
I expect great things from both Naples and Rome.
People who said Napoli are weak, maybe they haven't kept up with Napoli progress in recent seasons. They have performed well in several seasons, just they are still haven't been able to win a championship title. There are many factors that makes them fail including consistency after break/half season that may has been solved this season. However, Napoli performance this season, made me remember what Milan achieved last season. It could be that Napoli's unbeaten run from the beginning of the season until now is the right time of the success from team development they have done in the last few seasons.
