Borussia Dortmund won't sell Shinji Kagawa cheaply

Borussia Dortmund owner Hans-Joachim Watzke has insisted that the club won't sell midfielder Shinji Kagawa on the cheap.

The Japanese international only has one year left on his contract at the German club and has been linked with a move to Manchester United.

However, Watzke is adamant that Dortmund will receive a "princely sum" for one of their star assets, whom they value at around £17m.

"We all know the abilities of Shinji, his youth and the value he adds to this side," said Watzke.

"I also note what Bayern Munich paid for goalkeeper Manuel Neuer (€22m from Schalke last year).

"He also only had a year left on his contract. Given those facts we can certainly expect a princely sum for him."

Arsenal and AC Milan are also thought to be admirers of the 23-year-old.
