Amid concerns over his age, Lewandowski feels better than ever and believes he can play at the highest level for at least another four years.
He told Sport Bild: “I’m in good shape physically and have the right mentality.
“I can play for many more years; I’m sure at least four more years. And then I will see; maybe I can raise the bar even higher.
“This summer I had the best results in my career. If I was 27 a year ago, I am now either 25 or 26. My stats are better than ever.”
