Nuri Sahin has hinted that he could leave Real Madrid at the end of the season.
The 24-year-old Turkey international is currently on loan from the Spanish club to German outfit Borussia Dortmund.
"From the outside you can say that I failed abroad," the midfielder told Bild. "It was not meant to be, and I had my part to play.
"[Madrid coach Jose] Mourinho was always honest with me, always told me everything in private. It was an honour to work with him.
"I left on loan because I wanted to play, and Borussia are for me a matter of the heart. The end of the loan? In due course, the clubs will come together and find a good solution."
Sahin joined Madrid from Dortmund in the summer of 2011.
