Lewandowski is again being linked with Real this year.
But the 29-year-old refuses to be distracted by such talk and insists his full focus will be on helping Bayern continue to enjoy success as they close in on a sixth successive Bundesliga title.
"At the moment I do not worry about it," Lewandowski told Kicker.
"If I was to think about the Real speculation as a Bayern player it would not be good for me because I wouldn't be focused on my job here anymore.
"I'm a Bayern player and I want to give everything here."
