Despite Borussia Dortmundâ€™s continual denials that they have agreed a deal to sell Lewandowski , the legendary midfielder appeared to add fuel to the speculation that he will leave, but stay in Germany.
"I was on the road this week. I heard that Lewandowski has an agreement with Bayern. Only the date of the move remains undecided,' Matthaus told Sky Bundesliga.
"Lewandowskiâ€™s contract runs out in 2014 and Dortmund will only get a fee in 2013 - surely a high fee. I heard it was something between Â£20m-Â£25m, otherwise he will go to Bayern for free next year."
