Borussia Dortmund will only consider selling Mario Goetze to a foreign club.
Manchester United are eyeing the Germany international as an alternative to Inter Milan's Wesley Sneijder.
Bild Goetze and Dortmund have agreed he will remain for this season. After then, the Bundesliga title holders will consider transfer offers from abroad, should they be received.
However, should Bayern Munich make a bid for Goetze, it will be categorically turned down - no matter how much is tabled.
