Borussia Dortmund chief Watzke admits they could sell Chelsea, Man City target Lewandowski
"This is a very simple calculation. It may make economic sense after a good season with Lewandowski to cash in for as high a transfer fee for him as we can. But we are under no economic pressure to do something," said Watzke.
"There's always the possibility that we will, if he does not extend. To clarify one thing: we'll decide that alone. But of course we will discuss it also with him."
