Stuttgart general manager Fredi Bobic says they're determined not to lose young defender Antonio Rudiger.
Rudiger has been linked with West Ham United and confirmed earlier this month the interest of Manchester United.
Rudiger is a first-team player of our club," Bobic told TZ. "There are many attempts from clubs to persuade him to leave our club.
"And it's definitely not an easy thing for the player to resist these offers. We have said we are out to keep him at Stuttgart and it will be tough.
"Still we want to hand him a great future at our club."
