Milan is just a bad team in the first place, they have Gimenez, Felix and Walker, their performance aren't that bad actually, they can still perform. Bologna's squad is a combination of young players who not able to reach senior team, second tier players and old players who no longer playing in senior team, yet Milan still lose.
Better to sack the manager instead, maybe Italian teams good when they get managed by Italian managers too. Inter, Atalanta, Napoli, and Juventus are managed by Italian managers. Milan was better when Stefano Pioli was the manager.
Felix and Walker kicked out from their PL clubs due to the decrease on their performances. They're crap, and never expect big things from them. If they were still useful for their old clubs, they would never join AC Milan.
The lost against Bologna is kinda strange. They lost it with narrow score, but one of Bologna's goal was blatant handball, and i wonder how the referee was not annulled it to be handball.
What the hell is wrong with refereeing these days in all of top leagues.
