Robert Lewandowski has admitted he does not know how long he will stay at Bayern Munich.
Lewandowski, 27, has been linked with a move away from Bayern when coach Pep Guardiola steps aside in the summer.
While the Poland international insisted he is happy at Bayern, he did suggest that the position could change in the future.
Asked if he sees himself finishing his career at Bayern, Lewandowski told Die Welt am Sonntag: "As a professional footballer, it's hard to say.
"Many times I have heard players say such a thing and then comes another coach and they were no longer in such high demand. Or they got a very interesting offer.
"In any case, I feel very well at Bayern and will always give everything for the team while I'm here. I focus exclusively on Bayern.
"Ever since I was 18, there have been enquiries and rumours and even then I learned to deal with it. I can shut it out, it does not distract me.
"For me, this has become normal. However, it does not interest me."
Lewandowski has also backed Guardiola to be a success in the Premier League.
