Not only that, Serie A will now be more competitive and points are not much different before, Inter Milan is also still trying to keep chasing points while Napoli and Atalanta are still consistent as a strong team at this time.
as you said, Serie A is currently more competitive. The competition between teams is very visible. after the half of the season, we may see surprises coming from the teams that are currently lagging.
the winter transfer market could be one of the reasons for the improvement of the team that currently looks bad. I hope Juventus can improve its performance.
