The Rossoneri chief has revealed the club has agreed the right to buy the 22-year-old, currently on loan at San Siro, should he impress during his spell with the side
The 22-year-old joined the Rossoneri on loan during the summer transfer window, but Galliani has now revealed the San Siro outfit have agreed the right to buy the forward should they wish to keep hold of the player.
He told Milan Channel: "Nobody knows, but I've obtained from Barcelona a buy option on Bojan, which is lower than the one Roma had."
Bojan enjoyed a spell on loan with Roma last season, but was unable to secure a permanent switch to the Stadio Olimpico during the close season.
The former Spain youth international scored in Milan's 5-1 thrashing of Chievo on Saturday, in his fourth start for the club this campaign.
