The Rossoneri said farewell to several first-team members who will leave the club this summer during Sunday's 2-1 Serie A win over Novara, and vice-president Galliani feels a cycle has come to an end for the Rossoneri.
"We will miss these extraordinary champions, good men who kept the dressing room the way it should be. It's the end of an era," Galliani was quoted as saying on the club's official website.
"Milan are a club that love their players and it’s always mutual. I don’t mean only the ones who have been here for a decade but also those who, like Van Bommel have only been here a year and a half.
"The players who are leaving are doing so because they either think it’s the end of an era or because they want to play in a less demanding league. That’s the situation today, but there’s no certainty over tomorrow."
Milan finished the 2011-12 campaign in second position with 80 points from 38 games.
