Borussia Dortmund midfielder Shinji Kagawa is set to leave the club this summer after turning down the offer of a new contact.
The Japan international still has a year left to run on his current deal with the Bundesliga champions, but he is a player in demand - he has been heavily linked with Manchester United - and Dortmund are unlikely to want to run the risk of losing him for nothing next year.
"I had a meeting with his agent yesterday morning and Shinji Kagawa has informed us that he will definitely not be extending his contract," Dortmund director of sport Michael Zorc told the Bild newspaper.
"Should we now receive offers for Kagawa, then we will consider and negotiate them."
United manager Sir Alex Ferguson and assistant Mike Phelan were present at the DFB-Pokal final at the weekend as 23-year-old Kagawa scored in Dortmund's 5-2 win over Bayern Munich.
Kagawa will command a significantly higher fee than the 350,000 euros Dortmund paid Cerezo Osaka for him in 2010.
He has scored 21 goals in 49 Bundesliga matches, playing a key role in the club's back-to-back league titles.
