Borussia Dortmund's sporting director Michael Zorc has insisted that a deal has not been finalised for Manchester United to sign Shinji Kagawa.
Reports had claimed that the Red Devils had agreed to purchase the Japanese international for a fee believed to be in the region of £12m.
While accepting that a deal is likely, Zorc went on to admit that "there are some details still to be confirmed" before the midfielder becomes a United player.
Kagawa currently has one more year remaining on his deal with the German champions.
