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.
Although the opportunity for Verona to beat Ac Milan is always there. But that is indeed a very small opportunity and difficult to realize. Because the depth of the AC Milan squad and AC Milan's performance are much better in every aspect. AS Roma lost to Verona because at that time Roma had not been in good form since the start of the season. In contrast to AC Milan, which started the season with better performance. So for me this will be a fairly easy win for Ac Milan. But there is indeed a way for Verona to beat Ac Milan. Namely, Verona must make a strong enough defense from the start and only attack when they get the opportunity to counterattack. But it won't be easy. Because AC Milan's defense and attack are still better.
