Hoffenheim general manager Alexander Rosen insists that the club will not sell midfielder Sejad Salihovic.
The Bosnian international has been linked with Turkish side Kasimpasa even though he is contracted to the German club until June 2016.
But, speaking to Deutsche Presseagentur, Rosen was adamant that Salihovic would not be sold during the transfer window.
Rosen said: "Sejad Salihovic is a first-team player of our club and remains under contract with us.
"We have never received a transfer enquiry or official bid for the player from a club. This is a fact."
Salihovic made over 20 appearances for Hoffenheim last season.
