Currently there are still three teams that still have the potential to continue competing in terms of the fight for the title in Serie A and that will still make the competition even fiercer until the end of the season. The teams are the ones you mentioned, namely Atalanta, Napoli and also Inter Milan who are currently still leading the Serie A standings. And I still hope that all three can consistently win until the end of the season so that the determination of the Serie A champion this season occurs in the very last match.
I think the title fight is more favored for the two teams between Napoli and Inter Milan because So far they seem to be competing strongly at the top of the standings. For Atalanta, they don't have the mentality to be champions because I saw their poor performance when they were defeated by Inter Milan. The competition in Serie A is quite interesting because some of the big teams have lost their best form so that the Competition is dominated by other teams that have made better progress this season.
I am more confident that Inter Milan will succeed in defending the title because they have a stronger team and a coach who has succeeded in building a stronger squad. Just look at Inter Milan front line this season, they have been much more aggressive since Thuram was brought in. I think it will be difficult for napoli to stop Inter Milan progress in winning the Scudetto this season, although the points gap is not that far away, inter milan performance is much better to establish themselves as champions.
