Manchester United have been given encouragement over the signing of Robert Lewandowski, after Borussia Dortmund admitted they would have to factor in the economic conditions before making a decision on whether to sell their star striker or not.
United are the frontrunners for the signature of the 24-year-old, who is seen as one of the best forwards in Europe.
Ferguson has repeatedly sent scouts to watch the Polish international in action, while taking a look at the striker himself in the Champions League game against Manchester City.
It is believed Dortmund value the player at around £25 million ($40 million), and will be willing to let go of him if a bid matching that amount is made.
"We will have to make decisions in this case at the end of the season," Dortmund chief executive Hans-Joachim Watzke is quoted as saying by The Telegraph. "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 and it's our decision. It's not something to be decided by others. As often as I am talking to Robert, I do not have the impression he wants to leave us."
Lewandowski's current deal expires in 2014, and it is understood the Polish striker is keen on making a move to the English Premier League, having previously stated several times of his liking for the game in England.
United will look to get their player for much lesser than the £25 million, in the summer of 2013, seeing as he will only have a year remaining on his contract.
Arsenal have also been linked with a move for the striker, along with Italian club Inter Milan, while a bid from Manchester City or Chelsea cannot be entirely ruled out.
