At least, with these two wins will certainly make Milan have better morale to continue the Serie A competition. Because after all, if Milan are complacent and or feel satisfied with that victory, it could be something bad too if they cannot refocus on improving their position in the Serie A standings. But indeed, ofcourse it was an impressive victory too because basically it is not easy to get good results quickly with the new coach. But the truth is, Milan really did it and that success might also be a sign of Milan's greatness that other teams should watch out for as well.
AC Milan have been able to defeat two very strong teams like Juventus and Inter Milan in the last two matches. As a result, there is a great possibility that the confidence of Milan players will increase. But this season we have seen several times that Milan can play well against big teams but are unable to play well consistently.
AC Milan's overall performance in Serie A is very weak. AC Milan is in the eighth place in the points table. Milan has been able to win only 7 matches out of 17 matches. I would say that if the performance of Milan's attacking players improves, Milan will be able to play better in Serie A. But if the attacking players do not play well, it will not be possible for Milan to maintain its good performance in Serie A.
Yes, 2 wins when facing teams that cannot be underestimated can be something that will increase Ac Milan's confidence, especially since they also managed to become champions by defeating 2 strong teams, of course that can also make their morale even better. This is a good moment for Ac Milan to be able to rise in Serie A, because if they miss this moment, it will be a shame for them too. There is no time for them to celebrate their success in the Supercoppa, because they have to quickly return to play to be able to improve their ranking in the Serie A standings to be able to compete at the top.
