Borussia Dortmund chief executive Hans-Joachim Watzke says there will be no cut-price sales by his club this summer.
Currently fifth in the Bundesliga with six games remaining, there is no guarantee that Dortmund will qualify for Europe's top competition next season.
But if rival clubs think that will help them sign Dortmund's star men, Erling Braut Haaland and Jadon Sancho, Watzke says they are wrong.
"When Covid-19 struck, we had no debt. Not one euro. Because of that, it is a comfortable situation. We do not have to sell a player. That is important.
"The rich clubs in the world, they must know when they want a player from Borussia Dortmund there are two possibilities. The first is that I tell them they have no chance. Other times, I will tell them 'this is the price'. Then they must know this is the price. It is not another price.
"We are very clear. We are very honest." Said Watzke.
That is exactly the stance Dortmund took with Sancho last summer. Manchester United were told they could sign Sancho for a fee in excess of 100m euros. United felt that was excessive, but the price did not drop and the England man remained where he was.
This year, similar rumours are circulating around striker Haaland.
Dortmund entertain Manchester City in the second leg of the Champions League quarter-final on Wednesday, trailing 2-1 from last week's game at Etihad Stadium.
