Ljajic linked with Fiorentina move
The 18-year-old Serbian signed for the Red Devils in January 2009 along with Partizan Belgrade team-mate Zoran Tosic, with Ljajic remaining at Partizan on loan last year before being expected to join Sir Alex Ferguson's side this month.
However, with no guarantee of a work permit for the playmaker, United opted to pull out of the deal.
And, according to reports in Italy, the promising youngster - who has made 38 league appearances for Partizan since breaking onto the first-team scene in 2008 and has represented Serbia U21s on 10 occasions - is now a target for Fiorentina.
The Tuscans - who have fellow Serbian starlet Stevan Jovetic in their ranks - are thought to be keen to add more creativity to their side and consider Ljajic as the ideal candidate.
The Florence side are believed to be weighing up an €8 million offer for his services.
Ljajic has already turned down advances from both Rubin Kazan and CSKA Moscow, insisting that he is not interested in a move to Russia.
