Sunderland have made another enquiry for Borussia Dortmund forward Nelson Valdez, skysports.com understands.
Skysports.com revealed in May that the 26-year-old was on the radar of a number of Premier League clubs.
Clubs had previously been quoted around £10million, but now it has emerged that he is available for less than half that because of a release clause in his contract.
Valdez impressed at the World Cup finals with Paraguay and the interest from around Europe is growing.
His British representative Barry McIntosh is confident a move will soon be sealed.
"There has been numerous clubs in England that have been interested in taking Valdez, but unfortunately most of the clubs were put off by the asking price," McIntosh told skysports.com.
"We were aware of this clause and now Borussia have confirmed this, so we are confident a deal can be done as his desire is to play in England."
Dortmund's chief executive Hans-Joachim Watzke has confirmed that Valdez will not be sold for less than his release clause of €5million (£4.2million).
"It would be foolish to sell a player like (Nelson) Valdez for less than £4.2m," Watzke told Bild.
"Nelson has reached the quarter-finals of the World Cup with Paraguay and was the best player in the match against Spain."
The player himself has confirmed that he has options from across Europe, commenting: "There is a lucrative offer from the Netherlands I have received.
"But there is also interest from Russia, Portugal and England. My player agent is actually weighing up options."
Valdez's current contract expires in June 2012, and he has been with Dortmund since 2006 when he joined from Werder Bremen.
