In Jan the player made some noises about the lack of playing time but only through his agent...Barca reprimanded him but that has been Zlatan's normal tendency of playing through media whenever he switches across clubs.
From todays reports, his agent has responded to the rumours and its apparent he's whoring the player to other clubs, hasnt ruled out the possiblity of a move back to Juventus.
If he moves over from Barca, he would try to move to a club offers CL football. Inter- they wont pay £40M back along with wages to take him back. , Milan - they do not have cash at the moment they are cornering some German league rejects, Juventus - no CL, it can still happen Zlatan and Agnelli both come down and reach an agreement but in reality its more unlikely than Inter, Real Madrid - Barca wont sell the player to them.. Finally it should be a toss up between Chelsea and Manchester United..
