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.
From rank 4 to rank 8 there is still not that much difference in points. So some rapid changes could occur in the next few weeks. Like Lazio, which could be overtaken in just one week by Juventus, and vice versa, Juventus could also be overtaken by Fiorentina, which is currently ranked 6th, which is only 1 point different from Juventus. Well anything can happen. Moreover, currently there are still quite a lot of matches remaining this season, namely around 16 matches remaining this season. Which could actually also allow Napoli and Inter Milan to lose their position if these two teams start to falter at the end of this season. The competition for the title and competition for UCL tickets will be very fierce this season. Because it's quite rare for there to be such a small difference in points like this season.
