Borussia Dortmund have offered encouragement to Manchester United in their chase of Robert Lewandowski by hinting they could be prepared to listen to offers for the star striker.
Sky Sports reports how the Polish international has been heavily linked with a move to the Premier League as well as a host of other European clubs.
Lewandowski has netted an impressive nine goals in 15 Bundesliga appearances this season, prompting Red Devils boss Sir Alex Ferguson to firm up his interest in the 24-year-old.
After showing no great rush to sign a new deal with the reigning German champions, recent speculation has suggested one of Europe's most prolific strikers has had his head turned by the opportunity to move to Old Trafford.
He still has one-and-a-half years remaining on his current deal at the Westfalenstadion, but Dortmund executive Hans-Joachim Watzke told Bild that the club are already concerned about losing Lewandowski - to Manchester United or somewhere else - for a cut-price fee.
"As often as I am talking to Robert, I do not have the impression he wants to leave us," he said. "[But] we will have to make decisions in this case at the end of the season.
"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. We may decide on economical factors."
