Borussia Dortmund coach Jurgen Klopp insists striker Robert Lewandowski is not for sale.
The Pole is the subject of intense interest from Manchester United and Bayern Munich.
"We will not sell Robert Lewandowski - not for any price," Klopp told German newspaper Suddeutsche Zeitung.
"Our biggest obligation is to have a strong squad and one that enables you to play a successful game. He will remain at our club."
