AC Milan is the biggest disappointment for the Italian fans with their poor run in this season in this elite competition after three matches 2 points with no goal scored by them is surely not acceptable at this level even their performance in Serie A is impressive with currently they are at the second spot behind city rivals Inter Milan and having good start but now in last two games they lost against Juventus and now PSG surely creating problems for them and their fans with moral is down, and confidence level is also decreasing which could be not ideal for them.
Most chances we will have improvement in coming matches because now they will be regrouped themselves and try to have fight for the spot of next round even it's not easy but still it's all possible with all teams are on level just PSG is having enough space for the staying at the top of the group.
AC Milan is indeed in a pretty tough group so AC Milan is not able to compete with these clubs and AC Milan has not scored a goal at all for 3 matches in the Champions League, I think AC Milan chances of getting through to the next round will be increasingly difficult because AC Milan is getting stronger lagging behind in points.
However, AC Milan actually still has a chance to qualify if in the remaining 3 match in the Champions League, AC Milan is able to win the match without losing, but it does not looks like it will be easy because the competitors in Group F are quite difficult for AC Milan to overcome this seasons. I think AC Milan potential there only a little left to escape.
