That means there is no chance for Juventus to catch up with the points collected by Inter Milan and even AC Milan, which is in second place in the standings, is also unable to catch up with Inter Milan. Maintaining the top four is something even better because they can play in the Champions League next season.
Chance for AC Milan to catch Inter Milan in Serie A is small like chance for Bayern Munich to catch Leverkusen in Bundesliga. They both have almost no chance to catch the first teams in their leagues and can focus on their second position protection as only main task till their league ending.
AC Milan is indeed more comfortable in second place in the standings because they have points that are impossible for Juventus or Bologna to catch up with.
They look to be safe there with 6 points more than Juventus but it is too much difference and AC Milan must be careful to defend their second position. Risk to drop out of top four with AC Milan is very small, almost impossible.
Juventus need to be careful because if they play inconsistently then Bologna could catch up on the points they have collected, even though fourth place in the standings will also qualify for the Champions League. But for Juventus they should be able to maintain their current position because Bologna is not much better than them.
Juventus situation is like AC Milan with pressure from Bologna to defend their third position but it is almost impossible for Juventus to lose a position in top four to AS Roma. They have 7 points more than AS Roma after 31 matches so far and only need to play carefully to defend their position against Roma.
