Borussia Dortmund chief Michael Zorc expects Robert Lewandowski to leave Germany in the summer. The Pole is a top target for Manchester United and Bayern Munich.
Zorc told BILD: "In Germany, the boy has now gained enough experience. Now it's time he learned a new language. Switching to Bayern Munich? We never talked about this. The last time we closed a transfer with Bayern was to get Mats Hummels. It was certainly not among the worst operations.
"Lewandowski is among the three best strikers in Europe, so it is highly difficult to sell. During the three years with us he has grown a lot."
