Nurnberg are reluctant to allow Germany Under 21 midfielder Ilkay Gundogan to leave the club in a cut-price deal.
The 19-year-old is thought to have been the subject of €7million (£6m) offers from Bayer Leverkusen and Hoffenheim this summer.
But Nurnberg are understood to value Gundogan at €10m (£9m) and they are not prepared to allow the former Bochum youth star for anything less than that asking price.
General manager Martin Bader told BILD: "We have been telling both clubs who are interested in Ilkay that the player is not available for that sort of money this summer.
"We are not working on a transfer of the player if terms are like that."
Hoffenheim are therefore planning to bide their time before possibly making another offer at the end of the transfer window because they are confident that Gundogan wants to move.
Manager Ralf Rangnick said: "Ilkay Gundogan would very much like to join our club, but we are not prepared to match the terms and conditions of Nurnberg at this point in time.
"Basically we would have until the end of August to find a solution on this."
