Borussia Dortmund have reacted with frustration after reports emerged that Robert Lewandowski has secretly agreed to join Bayern Munich next season.
The German champions insist that Polish international Lewandowski is not for sale.
In fact, say Dortmund, their intention is for Lewandowski to see out his contract with them, and potentially sign a new one.
And they are adamant that if the 24-year-old from Warsaw is ever sold, it will only be on their terms.
"It's just a bubble of speculation," Dortmund’s general manager, Hans-Joachim Watzke said regarding the rumours that Lewa is Bavaria bound.
"There is absolutely zero substance in the reports, there's is not even a primary source - that really gets on my nerves.
"The fact is, Robert has a contract with us until 2014 and we want to extend that."
As the German media continues to speculate that Dortmund and Bayern simply need to agree a fee over Lewa’s departure, Watzke did however accept that it is fruitless to force a wantaway player to stay.
"If Robert doesn't extend his contract by the end of the season, then we will just do what we've always done, which is sit down together and discuss where things go," he told Der Spiegel.
"But we certainly wouldn't let him go for any old price."
