The Rossoneri's Vice President says that his club's new signing pushes his teammates on in the same way the Paris Saint-Germain striker inspires his side.
Balotelli has scored four goals in his three Serie A matches since arriving from Manchester City, and Galliani has praised the Italian's displays.
“Balotelli inspires the other players, sort of like the Zlatan Ibrahimovic effect," he said. "He gives strength, and his performances have a collateral effect on the others. His goals are proof we didn’t just buy him for his media impact.”
Milan, which currently lies third in Serie A following Friday's 2-1 win over Parma, next faces Barcelona in the last 16 of the Champions League.
Galliani says he believes his side has no reason to fear the Liga giant, but admitted the club could be without striker Stephan El Shaarawy while Balotelli cannot feature after appearing in the competition earlier in the season with Manchester City.
“Destiny means we have met Barcelona six times in two seasons, but we have no psychological weakness towards them,” he said. “We hope that El Shaarawy can recover in time for the match. It is fortunate we signed Mario Balotelli in January, as Giampaolo Pazzini has been injured and El Shaarawy is trying to recover from a knee inflammation.”
