A week full of surprises, when Milan & Inter failed to get 3 points, apparently in the match against Cagliari, Napoli also failed to get 3 points to shift Milan's position at the top of the standings. Quite happy with Cagliari, they seem to be inspired by Selernitana who managed to hold Milan to a draw. But, this results still not good for Cagliari, they are still in the relegation zone.
So, this week's Top 5 can only get a maximum of 1 point, nothing more. ha ha..
It was difficult to imagine such a situation even from the point of view of probability theory, but it happened. None of the TOP 5 could win.

I assumed that Cagliari would play very well at home, because they really need points, and where to earn them if not in home matches. They really looked better than Napoli and could even win this match, but probably a draw is a natural result.
