The midfielder has been linked with Barca.
But Lewandowski told BILD: "No. I only spoke to Jo about his situation at Bayern. There has been a lot of unrest and uncertainty there over the past few months. That can affect a team.
"But we only spoke as friends and former teammates, I didn't try to convince him to sign for Barcelona."
Regarding Harry Kane, his successor at the Allianz Arena, Lewandowski added: “He is a great striker, a very good solution for Bayern. Bayern spent a lot on Harry, he is a new dimension.
"The first year will not be easy for him, because the change is big. Harry needs time to understand Bayern. It is a challenge. He arrived at Bayern when he was 30, I arrived when I was 25. He is more mature and has more experience.
"On the other hand, I already knew the Bundesliga then. But Harry is one of the best strikers in the world.
"He will help the club, although there will be difficult phases."
