The 29-year-old has seen his future called into question on a regular basis during recent windows, with a big-money move away from the Allianz Arena often being touted.
Madrid has been mooted as a possible landing spot for some time, while Premier League sides such as United and Chelsea are also said to be keen.
He told Przeglad Sportowy: “I didn't think about it because I've been playing football for many years and this sort of situation has happened with all my transfers - whether it's from Znicz to Lech [Poznan] or from Lech [Pruszkow] to Borussia Dortmund or from BVB to Bayern.
“I've learned how to handle these situations.”
Lewandowski’s decision to make Pini Zahavi his new agent in February was considered by many to be a sign indication that he is ready to take on a new challenge.
The Israeli ‘super agent’ has claimed that the Pole is actively seeking a move elsewhere, telling Sport Bild in May: “Robert feels he needs a change and a new challenge in his career. The managers of Bayern know about it.”
Lewandowski has, however, revealed that he told Zahavi not to inform him of any interest during the World Cup.
He added: “Yes, it was exactly like that. From the very beginning of the group stage, I kept repeating: you are handling this and I'm playing. Do not write about anything and do not call.”
New Bayern boss Nico Kovac has spoken with Lewandowski about his future plans since inheriting the reins in Bavaria and claims to have been offered no indication that the prolific frontman is looking to move on.
He said: "I do want to keep the players here, but obviously I know things can happen in the transfer market. Currently, there's nothing to report.
"I was on the phone with Lewandowski and told him my opinion. I'm looking forward to working with him. He's a world-class striker who has achieved a lot at this club [and] in the future will continue to perform that way."
