Borussia Dortmund would only sell teenage star Mario Goetze to a foreign team and have ruled out selling him to any other German league club, CEO Hans-Joachim Watzke insisted on Wednesday.
The transfer window closes on August 31, but German champions Dortmund insist their star player is not going anywhere - especially not in Germany.
"In all seriousness, Mario does not have the idea to change to another team within Germany. You can completely forget about it," Watzke told German magazine Sport-Bild.
Europe's top clubs have taken interest in the German teenager after a string of top-class performances.
English giants Manchester United have been reported to be particularly interested after talks with Inter Milan's Wesley Sneijder fell through recently.
Goetze, who scored and orchestrated Germany's 3-2 friendly win over Brazil in Stuttgart last Wednesday, has already said he will never join German giants Bayern Munich.
The 19-year-old has a contract at Dortmund until June 2014 after signing a contract extension.
Even if Bayern, who bought Germany goalkeeper Manuel Neuer from Schalke and defender Jerome Boateng from Manchester City during the summer, did offer a multi-million euros bid, Watzke says Dortmund would be stupid to let him go to their rivals.
"Bayern can save themselves an offer, we would be totally stupid to let him go there," said Watzke.
"Mario has won the German title with us, he has been with us for eight years and his family lives in the city.
"So there are only three or four clubs in the world he could possibly move to. And they are not located in Germany."
