Sydney FC's impressive Serbian contingent looks set to grow to three with the club closing in on the signature of former youth international Milos Dimitrijevic.

The 29-year-old midfielder arrived in Sydney on Sunday and has started training with the Sky Blues with a view to signing a six-month deal.

With fellow Serbs Nikola Petkovic and Ranko Despotovic the club's two best players this season, club chief executive Tony Pignata said Dimitrijevic had been identified as a player who could make an immediate difference in midfield.

''One of our European scouts over there told us about Milos and and we're very keen to have a look at him,'' Pignata said. ''We'll see how it pans but we've heard a lot of good things and Nikola gave him a great character reference. He's played some for some big clubs in Europe and that's a good sign of his pedigree. He's already done his medical at training this morning.''

The issue for the Sky Blues is that while they want to sign Dimitrijevic, they already have a full squad and will have to release a player before adding him.
