Shinji Kagawa says no deadline has been set on signing a new contract with Borussia Dortmund but remains hopeful a deal can be done to keep him at the club.
The 22-year-old Japanese playmaker's current contract with the German champions expires at the end of the 2012-13 campaign.
Kagawa has many reported admirers including Arsenal, Manchester United and Milan, and with BVB CEO Hans-Joachim Watzke telling Sport-Bild last month talks on a new deal had broken down there has been speculation he will leave the club.
However, Kagawa, who said in February he was having a "terrific time" in Dortmund and wanted to stay, told Reviersport this week that negotiations with the club were ongoing.
"Of course we are in constant contact, but that is all up to my advisers," Kagawa said.
"We have set no deadline, but we are in talks and I hope that the club has something nice in the mix."
The former Cerezo Osaka man, who joined Dortmund ahead of the 2010-11 season, has scored 11 goals in 31 appearances in all competitions for his club this term.
