The latest reports saw Milan this month forced to deny claims that it plans to sell a stake in the club to the Qatar sovereign wealth fund or other investors.
Italian newspaper Gazzetta dello Sport had reported that owner Silvio Berlusconi was considering selling a 30% stake in Milan for Eur250 million.
Gazzetta said the investment could help Milan pursue plans for a new stadium or redevelop the San Siro.
However, Galliani told Sky Italia: “President Berlusconi has always said that new investors are welcome and the doors are always open. However, I can assure you 100% that right now there are no buyers.”
