I wouldn't call Genoa a disappointing result. Because Genoa's chances of scoring points against Milan were slim. Then the Genoa players played a great defensive game. And I thought maybe Genoa would be able to get 1 point in this match. It's sad for Genoa. They conceded the goal at the last moment.
Both Genoa and Milan tried to keep their defense tight in this match. We did not expect such a performance from Milan. Because this team is expected to fight for the title this year. If Milan want to win the title, they need to play better. Otherwise it will be difficult for the team to maintain consistency.
Yes, it looks like AC Milan's performance in this match was not good even though they won this match. AC Milan should have been able to win with a big score against a weak team like Genoa, but in fact Milan also played below their usual performance in this match.
I also doubt that Milan will compete fiercely at the top of the standings if their performance continues like this.
There are many things they have to change, especially in AC Milan's front line which in my opinion is less sharp in completing scoring opportunities and also their midfield which is less creative.
There was a bit of luck for Milan's victory in this match after a series of drama at the end of the match which was very interesting to enjoy.
