Dortmund CEO Hans-Joachim Watzke told Bild on Monday that the club would not sell the Polish striker to their Bundesliga rivals this summer under any circumstances but he did the leave the door open for potential move to a Spanish or English club.
This has not satisfied Lewandowski though, who Dortmund risk losing for nothing next summer when his contract expires.
"He (Watzke) recently told me something different. He knows what I wish for," Lewandowski said at an event in Warsaw in quotes picked up by ESPN.
"He has promised me that I will be allowed to leave, and now something different happens.
"But I think everything will change. In my opinion, this is not the last decision, and I believe everything will change and come to a good conclusion. Everyone at Borussia Dortmund knows what I want and where I want to go to."
In his quotes to Bild though, Watzke insisted that Lewandowski would have to wait 12 months if he wanted to join Bayern.
"Robert Lewandowski will definitely not transfer to Bayern Munich in 2013. This is final. We have informed Robert and his advisors. The Bayern case is closed because there was no written offer," Watzke told the paper.
"There were two phone calls in the past four weeks with Bayern. We told Bayern that due to stock exchange rules (as Dortmund are a listed company), we need a written offer for Lewandowski. But until today, no offer has come in.
"If Robert wants to go to Munich he will have another chance next year.
"I am not saying he will definitely stay but he will certainly not be playing for Bayern in 2013."
