Borussia Dortmund's club executive Hans-Joachim Watzke has hinted that the German champions could listen to offers for striker Robert Lewandowski.
The Polish international has been linked with a host of clubs in recent weeks, including Manchester United and Juventus.
Despite insisting that the decision will be down to Dortmund, Watzke conceded that they may be forced to part with the 24-year-old because of "economical factors".
"As often as I am talking to Robert, I do not have the impression he wants to leave us," Watze told Bild. "We will have to make decisions in this case at the end of the season. We may decide on economical factors.
"Would it be best to cash in a big fee? Or would it be even better to keep Lewandowski to ensure we are more likely to qualify for the Champions League with him in our side, as this would guarantee us big income?
"It's a decision we will have to take. It's our decision. It's not something to be decided by others."
Lewandowski's contract at the Westfalenstadion is due to expire in the summer of 2014.
