Borussia Dortmund have been rattled by interest from Manchester United in star midfielder Mario Goetze.
Dortmund are aware that United boss Sir Alex Ferguson has Goetze under consideration and is now pondering bringing forward plans to bid for the midfielder after being frustrated in talks for Inter Milan star Wesley Sneijder.
An offer of €25 million has been mooted, but Hans-Joachim Watzke declared:. "No matter which club want him, our answer is always the same: Mario is not for sale."
