Robert Lewandowski says he will decide on his future once the season is over - after reports claimed he had already agreed a move to Bayern Munich.
The in-demand Borussia Dortmund forward has been the subject of much transfer speculation this season, with a host of top European clubs linked with the Poland international.
Reports from Germany this week suggested the player had already agreed a deal to move to Bayern, who will be managed by Pep Guardiola next season.
But the player told Sport-Bild that the subject has "to cool off" and that "we'll talk after the final match of the season and we'll see."
The Poland striker says his decision will come after consulting with his agent and considering all offers.
And Hans Joachim Watzke, the Dortmund general manager, said that no deal had yet been completed.
"It's just a bubble of speculation," he said. "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."
However, Watzke said if the player, who has scored 13 goals this season, did want to leave, they would not stand in his way.
"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 Spiegel magazine.
"But we certainly wouldn't let him go for any old price."
