Sometimes the impossible can happen, including for Verona when they play against a much stronger team. We can see when Verona managed to beat Roma and this incident could happen again against AC Milan. But of course Verona must press from the early minutes so that their goal is successful and don't be caught off guard when AC Milan attacks. I think if Verona manages to score a goal first and then they do total defense, I think the result they want can be realized.
I don't think it will be that easy, mate, because Verona is not facing a team with a different quality, so Verona has to consider more that their opponent this time is a better team than AS Roma, so the pressure and hard work must be there from the start of the match if Verona wants better results at San Siro. But I'm not sure that Verona will be able to win there because AC Milan is also aiming for victory at home in order to stay close to its true rival who is at the top of the Serie A standings now.
Actually there is no need doubt to Milan, it is clear that they are aiming for 3 points because they have lost the previous match and Mila will not let Lecce take 2nd place
Based on the schedule, Milan has 2 easy matches ahead then at the end of the month they will play Lazio, well in this match there is no guarantee that Milan can get points, therefore Milan must secure the previous 2 matches if it fails then Milan will be thrown out of the top 4.
