The 67-year-old has slammed critics of the club, reminding them of the achievements over the past quarter of a century
Massimiliano Allegri's men have dropped points against Napoli, Lazio, Juventus and Udinese already this term, but bounced back on Saturday with a convincing 3-0 win over Palermo, and Galliani feels his team are no worse than their title rivals.
"I've heard far too many things that I have not liked around AC Milan lately. We are talking about a club that have won 28 trophies in the last 25 years," Galliani said, according to Il Corriere dello Sport.
"If I had to go along with all the talk, I would be saying that the three points against Palermo were useful in staving off relegation, that we are poor because we bought players like [Alberto] Aquilani and [Antonio] Nocerino, while Napoli and Juventus spent money perfectly.
"This is not right. I don't understand this attitude and I do not agree with it."
Following Saturday's victory, Milan sit in 13th place in Serie A, four points behind leaders Juventus.
