The championship fight between Napoli, Inter and Atalanta is still ongoing. There is a one point difference between Napoli and Inter and Inter is a little bit far from their old performance. While everyone expected a better performance from them, we can say that they were overshadowed by Napoli this year. When they experienced unexpected points losses, Inter naturally ranks second behind Napoli. If we think that this race will continue until the end of the year, I think Inter's chance at the championship will continue until the last weeks.
The way am seeing events unfolding it is very uncertain to me who'll be the title holders of Italian serie A this season, the one point difference as you said is more reason why we can't conclude we will win the league race, Though Atlanta is in the third position of the league standings but am not seeing them as a team that'll lift the trophy, yea anything can happen but Atlanta has shown a sign of weakness recently, there form has also droped though the won Verona but i wouldn't be seeing as a good sign of improvement until they continue wining so as it is, the two teams we can confidently speak for is Napoli and inter milan, inter is a good side despite the few points drop, as i said earlier there's still uncertainty surrounding the League title this season though things may get clearer as time goes by.
