Manchester City are understood to have made a move for Partizan Belgrade starlet Stefan Savic.
City have been linked with a string of defenders and, with Jerome Boateng looking likely to depart for Bayern Munich, manager Roberto Mancini will be looking for reinforcements.
Bolton's Gary Cahill has been tipped to move to Eastlands, but Savic now appears to be at the top of their agenda.
Serbian sources claim City have opened the bidding with a €7million offer for the 20-year-old stopper.
But Partizan are believed to be looking for at least €10million for the Montenegro international, who is regarded as one of the best young defenders in Europe.
Partizan's sporting director Mladen Krstajic insisted that a deal had not yet been struck.
"Savic is still here with us, so he has signed nothing yet," he told Blic.
The Serbia media claim that Partizan would like to keep Savic for their Champions League qualifying campaign, through July and August, before letting him depart for England.
"If the time comes for me to leave Partizan, it would be difficult - but that is our life in sport. But for now I have no transfer information," said Savic.
Savic joined Partizan last summer after previously spending time on trial at Arsenal and, although he would not automatically qualify for a work permit, his huge potential would almost certainly see him granted a move should City finalise terms.
The likes of AC Milan, Roma, Sporting Lisbon and Porto are also understood to have been tracking Savic in recent months.
