The Italian is full of admiration for the Blaugrana and believes that they are a fine advertisement for football, but he will not sell the Catalans his Brazilian center back.
The defender is already on the record saying that the Blaugrana approached him about moving to Camp Nou last summer but, the Rossoneri intend to make the Brazilian their new club captain in order to persuade him to remain at San Siro.
However, Galliani claims that the Italian champion is unwilling to listen to offers for the 27-year-old center back anyway.
"If Sandro Rosell asks me about Thiago Silva, my answer will be courteous but firm. He is not for sale," the Rossoneri chief is quoted as saying by Tuttosport.
Galliani has the utmost respect for Barca but is still hopeful that Milan can upset the Catalans in the first leg of their eagerly-awaited Champions League quarterfinal tie at San Siro on Wednesday.
"I always follow the games of Barcelona as they are a fantastic team," he enthused. "I really like the way they play, they are a great advertisement for football. Tonight [Wednesday] they are the favorites, but there are many champions in football and sometimes the favorites lose."
Milan's meeting with Barca at the Giuseppe Meazza gets underway at 2:45 p.m. ET.
