Stoke boss Tony Pulis insists he is eager to keep Tuncay at the club despite revealing German club Wolfsburg have made a bid for the Turkish striker.
Pulis confirmed that strikers Tuncay and Ricardo Fuller have been the subject of offers.
He said: "The club have received a bid from Wolfsburg and the clubs are talking but we are keen to keep Tuncay if we can. Sunderland also definitely made a bid for Ricardo. Not good enough? I'm not saying that. I'm just saying Sunderland made a bid and the clubs are talking."
Pulis also saluted FA Cup hero Thomas Sorensen and now wants to sit down to discuss a new contract with the veteran goalkeeper.
Sorensen has lost his first-team place in recent months to Asmir Begovic and has not started a Barclays Premier League game since October.
But the former Denmark international proved his worth with a last-minute penalty save from Wolves midfielder Nenad Milijas to secure Stoke a 1-0 fourth-round win at Molineux.
Pulis said: "Thomas has been brilliant. We are hoping to sit down and do a deal with Thomas to keep him at the football club.
"Begovic has been outstanding for us. As a young keeper, he has been outstanding.
"Thomas has been waiting patiently. He has been terrific. That is what you want, good competition."
