Milan have formally admitted their dissatisfaction with having to play Cagliari in front of a full Is Arenas.
The Isolani will face Fiorentina tomorrow behind-closed-doors after police and city council members declared the ground unsafe.
However, the Rossoneri are one of seven teams this term to play the Rossoblu at their stadium with supporters.
Back in February, Massimiliano Allegri's men drew 1-1 with Cagliari, and a statement on their official website has claimed that Serie A has been 'altered' this season.
“The League announced that the Cagliari-Fiorentina match will be behind-closed-doors,” the statement read.
“Milan had to play on February 10, 2013 in front of a full stadium, along with six other teams.
“Three teams played in front of season-ticket holders and three other behind-closed-doors.
“Only one, Juventus, was on a neutral ground. And in one case [Roma] the game was forfeited and given as a 3-0 win.
“This decision is one that any reasonable person would consider incomprehensible because identical cases have dealt with differently.
“It is certain that the normal course of Serie A has been altered.”
