The 37-year-old has experienced reduced playing time under Hansi Flick this season and says he is approaching his next move with patience and careful consideration.
After scoring 42 goals across all competitions last season, Lewandowski has only 14 so far this term.
With Ferran Torres emerging as Flick’s preferred striker and Lewandowski limited to just 10 La Liga starts, questions about a potential decline have surfaced.
"What is good is that I don't have pressure," Lewandowski told Sky Sports.
"At 30 or a few years (younger), this kind of feeling is going to be different... But in this moment, I don't have to know. I have patience. I'll give myself around three months to decide what I want to do. Me, just me."
