Red Star Belgrade sporting director Blazo Raosavljevic has revealed that his club will strongly oppose any January interest in their star talent Marko Grujic.
A number of European clubs have been strongly linked with the 19-year-old, who came through the academy at Red Star and is fast closing on 30 league appearances for his Serbian club.
Despite the amount of interest, Raosavljevic has said that Red Star will do everything they can to stop the teenage midfielder leaving until at least next summer.
"Lots of clubs want the player, Napoli are also courting him. However, we have not received any offers at the moment. If one came in now for 6m euros (£4m) I would reaffirm that our goal is to avoid selling the player until August 31, 2016," Gazzetta dello Sport have quoted Raosavljevic as saying.
Everton, Manchester United, Chelsea and a clutch of Serie A clubs have all been credited with an interest in Grujic.
