It is really not satisfying to see Milan in this condition. I mean I know they have been trying to fix things recently but they started the national break with a bad result against Fiorentina.

As far as I can see, there are some inner problems there too. For example, in the Fiorentina game Fonseca tried to explain his players that the main penalty taker of the team was Pulisic. But Theo and Abraham took those penalties and missed both...
Fonseca really needs to work on this topic. He should teach his players to respect and obey his choices. Otherwise this team can't be successful much this season. It's no joke.
It is very difficult for Fonseca when his relationship with the players and even between players is not harmonious, Fonseca as a coach seems not appreciated by the players, it is very disappointing for a team that is trying to rise and I think if Fonseca does not succeed in making changes to the discipline of the players then he will never be able to make AC Milan's performance better.
All the changes that have occurred in the AC Milan team this season have indeed made them very difficult and I think that is normal for a team with a new coach, everything takes process and time.
