Borussia fear United's Shinji charade
Borussia Dortmund have issued Shinji Kagawa with a deadline amid claims that he has been tabled a three-year deal by Manchester United.
The German champions have given their Japan playmaker an ultimatum - sign a contract extension by Monday or it will be withdrawn and they will begin actively looking for his replacement.
German daily newspaper Bild reports that Kagawa, whose 13 goals in 29 games helped Dortmund retain the Bundesliga title, has been given the deadline to extend his contract for three more years until 2016.
But according to their sources, United are ready to double his current wages with a three-year deal of their own waiting for him at the end of the season - with just the matter of a transfer fee to be arranged with Borussia.
"The fact is that he has had an offer put in front of him long ago which raises a few doubts, because up until now he hasn't reacted," said Dortmund president Reinhard Rauball.
"It is a good offer! He won't be getting peanuts at Dortmund.
"There still hasn't been contact from another club. As far as I am concerned, nothing has been decided, although I now have a slight tendency towards scepticism."
Borusia fear United's tactics over the move will mirror their approach to Bayern Munich over Owen Hargreaves which soured relations between the clubs.
Kagawa joined Borussia from J-League side Cerezo Osaka for 35,000 euros in 2010 and the Bundesliga champions can expect to make at least 250 times that amount id he departs this summer, with one year left on his current deal.
