Actually AC Milan is just three points away from Juventus which I don't see to really be a big deal in that Juventus can still be able to meet up or probably displace them depending on whatever the case maybe, if Juventus gets to win their next game they will be at equal points with AC Milan except if AC Milan aswell gets to win their own next fixture too but if it happens that they draw or win then Juventus will still be behind them.
The both team are currently on a tight position because they have a very close points but right now AC Milan is on a better chance because they have 3 point over Juventus and even if Juventus succeeded in wining there next match they may likely not going to beat AC Milan do to the fact that they will still be on equal points with AC Milan, and AC Milan still have a very good opportunity of increasing there points the more over Juventus because there next match will be against Fiorentina and from there performance I would say that AC Milan will win the match.
