Bayern Munich midfielder Renato Sanches cannot guarantee staying in Germany this summer.
Amid claims of Bayern seeking a cut-price £26 million to sell him, the Portugal international refused to shut the door on leaving.
Manchester United and PSG are being linked with Sanches and he declared to Record: "It's a great club. You never know what the future will be, but in principle, I will stay.
"If so, I would not be discouraged. I want to stay and give everything. I will redouble my efforts. Of course, I need to play more. With more playing time, I gain confidence and I feel better."
