Mladen Petric believes Hamburg would be willing to cash in on him for the right price after he was linked with Wolfsburg.
The Croatia international striker only joined Hamburg from Borussia Dortmund last summer, but is worried for his future at the Nordbank Arena.
He says he has not spoken to club officials recently about his situation, but is happy to be wanted by champions Wolfsburg.
"It's two weeks since someone from my club has contacted me," Petric told Bild.
"I am getting slightly unsettled and I am getting the feeling the club would be prepared to listen to good offers for me.
"I am very impressed by the fact Wolfsburg keep being interested in my services, although the club did reject their first proposal."
Wolfsburg executive Jurgen Marbach confirmed the title winners are keeping a watching brief on Petric's situation at Hamburg.
Marbach said: "We have been told Mladen Petric is not for sale, however we are staying very interested in him as a player."
Hamburg's general manager Dietmar Beiersdorfer, however, is adamant the club are not trying to offload Petric before the start of next season.
Beiersdorfer stated: "We told Mladen and his agent we do not have the intention to sell him."
