Milan obtain Krkic option
The 22-year-old joined Milan on loan in August, but Galliani has now revealed the San Siro outfit have an option to buy the forward should they wish to keep hold of the player.
He told Milan Channel: "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.
