Borussia Dortmund have warned Manchester United boss Sir Alex Ferguson off their Japanese star Shinji Kagawa.
Kagawa admits he is excited by the interest of United.
But Dortmund general manager Michael Zorc told Bild. "Kawaga's sale is not an issue.
"Ferguson can save himself the offer. Our ambition is even to extend Shinji's contract early.
We'll discuss everything with him when he returns from holiday."
