Next time the lead might change hands in the standings. Because there are matches like Roma - Napoli and Atalanta - Lazio. In case Atalanta win and Napoli lose, the new leader would be Atalanta. However it is really not easy to see this. Even though Roma are in a pretty impressive shape and they are playing home, Napoli are still a huge threat to them with their form. You must be remembering the Milan - Napoli match which Napoli defeated their opponent. Maybe they can do the same to Roma also unless Roma become very careful.

It isn't easy for Atalanta to win either. Lazio are one of the strongest teams of the recent weeks. I wouldn't be surprised if it ends in a draw.
