I'm guessing that Napoli will main the second position, judging from their previous games & statistics.
One month ago, I believed the gap between Napoli and Roma still be far based on statistic, but in fact it has been just 2 points now. I dont know if its because of Higuain banning, but Roma could overtake Napoli anytime if Napoli still get bad result on next match.
if they see their fight from the beginning until now, very decent AS Roma is in second position, just below Juventus.
