The last time Milan had this many, or more points after 17 rounds was when they won the scudetto in 2003/04. Even their CL winning/final teams in 2003, 2005 and 2007 didn't have 40 points after 17 rounds. Inter are also having one of their best seasons points-wise in the last decade. Both teams have drastically improved compared to those times you mention. The second reason is of course Juve not winning enough. So far we are doing almost the same as Conte's 2011/12 Juve. We won it back then against Milan which had 37 pts after 17 rounds.
