Why do you think that Milan would win Inter in the finals. I believe Inter will not lose gaurd their defense the way they did in their last meeting. However, the match is unpredictable because both teams are rivals to each other. Milan needs to buggle up their belt and take the rest of their matches serious, if not they might not qualify for any European competition next season.
Actually, Milan has also proven itself when facing Inter in the Super Cup final this season so I also have confidence that Milan still has the ability to break Inter's strength when they meet again in any event. As for the ranking in the standings for Milan, they also still have the opportunity to be in a better position so they can return to other European competitions in the coming season.
