I think Milan is in more danger here. Just look at their goals conceded. Plus losing to Sassulo shows just how vulnerable they are. If they don't get the penalty shot support from the refs like they did in the first 60% of games I could see them dropping down from 2nd.
News out of Juve is that players are kinda getting healthy. Something that the team hasn't had for most of the season. Nagging injuries to Ronaldo and Dybala aside, Juve now has Cuadrado and Bonucci healthy again. Even Dybala is playing again which is super important because he is Juve's only number 10. With a healthy Dybala Juve is now a threat from central and the right side. Now if Pirlo can somehow manage to write Buffon's name on the team sheet for the last few games and Inter start to screw up as is their tradition, things could get kinda interesting down the stretch.
One can hope this happens at least...
