Juventus and Milan are no longer in the title race - Juventus have 37 points, Milan could have 37 if they win a game in hand. Napoli have 53 points, an advantage that is almost impossible to catch up with. The title is actually fought for by two clubs - Napoli and Inter (equal number of lost points), with Inter the favorite according to bookmakers. Overall, I am pleased with the fact that the title race is competitive, plus the fight for the top 4 is no less competitive, where Juventus and Milan risk losing.
Of course, Milan and Juventus couldn't meet up to be among the title contenders this season because of their inconsistencies, and not having the zeal to improve their performance in order for them to meet up to the standards of Napoli and Inter. It was towards the end of last season that I had the feelings Juventus will not be among the top four this season due to the constant decline in their performance.
Milan and Juventus may only try to improve their standings as well as chasing the top 4 and for the championship title fight can only be continued by Inter Milan with Napoli who are currently at the top of the standings and in second place, I think Juventus and Milan are experiencing stagnant condition with no significant improvement now.
There are still many match, don't be too pessimistic because surprising things can happen if it only to occupy the top 4 later.
I just checked the table to see that Juventus is on 5th position with 37 points, two points behind Lazio. Since Juventus is a strong club, they will likely overtake Lazio with time, because I don't think that Lazio will be able to maintain the 4th position till the end of the season. Perhaps, the fourth position is open for the clubs on 4th-8th position on the table currently due to little point difference.
