Is Zlatan Ibrahimović still a FC Barcelona player? or is he now a AC Milan player?

I know he was loaned to AC Milan couple months ago, but is he still a Barcelona player? or did AC Milan bought him out? I haven't heard anything about this guy... and I'm just curious if Barcelona may use some money... by selling him so Barcelona can use more money to bring A.Sanchez and Fabregas... hopefully...
