Hans-Joachim Watzke, chief executive of Borussia Dortmund, has admitted that the club could sell star striker Pierre-Emerick Aubameyang if they received a big enough offer.
In recent months, the Gabon international has been linked with moves to both Real Madrid and Manchester City, with Watzke opening up for the first time on the forward's future.
"You can never guarantee that a player will stay at Borussia Dortmund forever but our strength is that we will always find replacements," he told Kicker TV.
"If there was an offer of 80 million euros then we would discuss it with the president and sporting director. If there was an offer like that, we'd also have to meet with Pierre-Emerick.
"You always have to evaluate different situations but there is no pressure on us. I would prefer that no offer arrived."
Previously, Aubameyang has admitted that he has a promise to his grandfather to one day pull on the Real jersey.
