Udinese are among clubs interested in Serbian starlet Filip Kostic.
The 19-year-old currently plies his trade with Radnicki 1923.
"Scouts of many clubs have been following him in recent months," agent Zarko Pavlovic told Kragujevac.
"There are talks every day, but we will not sell him for less than our valuation. We want €2million (£1.7m) for him and anybody that wants him will have to pay that sum.
"If you ask me, he will probably leave. He is a really great talent.
"We could also use the money to strengthen our team in many positions."
