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.
That can happen if Juventus make a difference by improving their performance and Milan have a little problem from performance because after all, even though 3 points are still very small and can be caught up but it will be a little different story when Juventus cannot improve their situation in terms of current performance.
Juventus' current condition is still not very good and it is inversely proportional to Milan, who are indeed getting the momentum to make a positive trend for them.
Currently, there are still about 9 matches left before reaching the finish but this is precisely what can backfire because sometimes consistency becomes increasingly difficult here. For example, last season for Inter, which was already very comfortable in second place, was overtaken by Lazio, who did play well at the end of the season and several clubs above Lazio had previously experienced a decline in performance. Currently Juventus are still in a difficult situation and even in terms of goal productivity they are still very weak so in this case there needs to be a big change by Allegri if they still expect second place in Serie A this season.
