Huntelaar, who is out of contract at the end of the season, has been linked with a January switch to the Serie A champions in the Italian media.
"As far as I know the rumours are to be catalogued as rumours and have to stop," Arnold Oosterveer told calciomercato.it. "There has been nothing concrete from anyone.
"As yet, we have not decided whether to renew with Schalke, but we have not talked to any other clubs either."
Huntelaar has scored 55 goals for Schalke since his move from AC Milan in summer 2010.
