The Polish striker is nearing the final year of his contract and so the reigning German champions could sell this summer, alerting potential suitors to his availability
The Polish striker, who has bagged nine goals in 15 Bundesliga starts this season has garnered attention from several clubs, including Juventus and Manchester United.
As exclusively revealed by Goal.com, the Bianconeri have already made an enquiry for his services, and with the 24-year-old's contract to expire at the end of next season, BVB could be forced to cut their losses.
"As often as I am talking to Robert, I do not have the impression he wants to leave us,” club executive Hans-Joachim Watzke told Sport 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."
