Calhanoglu has declared he wants to leave HSV for Bayer Leverkusen, but his club are unhappy that Bayer are refusing to offer more than £12 million for the youngster.
The question is, however, whether Calhanoglu would be prepared to move elsewhere should HSV accept a higher bid.
"I will definitely leave HSV," he said. "From my perspective, for the coming season I see myself clearly at Bayer."
