Woltemade reported for pre-season training on Monday at the camp in Tegernsee, prompting Wohlgemuth to reiterate Stuttgart's stance on the player.
The sporting director told Sky: "There is no new position. Nick will very likely be part of our squad this season as well. We have communicated this clearly and unequivocally to the public.
"It is our responsibility to focus on what will help us start a good new season. That's why we are only dealing with relevant issues. And an early transfer for Nick under the current circumstances is simply not relevant."
