Carlo Ancelotti has turned down the chance to return to AC Milan, telling the club he needs rest.
Jose Mourinho insists Diego Costa is content at Chelsea in response to reports linking him with a return to Atletico Madrid.
Reported AC Milan, Barcelona and Man City target Serdar Tasci says Stuttgart have received no offers from interested clubs.
Tasci is contracted to his Bundesliga employers until 2014, but a big-money bid would be expected to free him from that agreement.
Stuttgart appreciate that they would struggle to fend off interest from the most powerful sides on the continent, but hope to persuade Tasci to stay put.
The 25-year-old claims that is his intention for now, with reports suggesting that he has already held talks with potential suitors wide of the mark.
"I have not been approached," Tasci told Kicker-Sportmagazin.
"I have split from my agent this summer. If a club was keen, that club would have to speak to me and (general manager) Fredi Bobic.
"He would tell me if something happened and up until now nothing has.
"I can assure Bruno Labbadia (manager) that I have no interest in leaving Stuttgart at this point in time."
