seems to be difficult to shift Napoli at the top of the current standings. even in this season. because Napoli really have not shown a gap. they tend to be able to maintain the solidity of their game. for Atalanta then it could be that his position will soon be shifted by Milan. Because Milan are slowly starting to rediscover their best game. and indeed this season is still long. so we don't know what will happen from the start of the mid-season.
It's hard, of course it's true. I think Napoli are very strong so far beaten by any team in Serie A but I'm sure they will also be beaten later because other teams also want to get good results. Considering some of the big match, it seems possible to expect a Napoli defeat.
I think some of these teams can make Napoli drop points; Milan, Atalanta, Inter, Juventus and Roma. All of these teams are top teams in Serie A and it is possible to expect them to do well. So nothing is impossible, Napoli are good but they don't always win.
Napoli is a good competitive team and in last few years they are starting season with their best, but sadly every season near end they chock which hurt them badly even mostly they stayed in top four and have their seat into Champions League, but they need to stay same level for having better chance for winning title which is not happening, but this season is also having good start and with their way of play most likely they could be stayed strong, and we will watch good entertaining end with four to six teams are currently had chance for title and this could be good for Italian league because after few years we have improvement and quality soccer even results are still unpredictable and few teams are having problems but things looking positive.
