Hannover chairman Martin Kind insists goalkeeper Ron-Robert Zieler will not be sold this summer.
The 22-year-old former Manchester United youth player has emerged as the first-choice shot-stopper at awd-Arena since displacing Florian Fromlowitz in January.
Zieler's form has seen him linked with a move elsewhere, but Kind wants to agree a contract extension with the ex-Northampton loanee.
Kind told spox.com: "Ron-Robert Zieler is a player of our club. No other club needs to come up to us about him. They should rather be keen on other things.
"We will not sell. We want to modify his existing deal at our club. We plan to further extend his contract."
