RB Leipzig chief Oliver Mintzlaff admits Dayot Upamecano could be sold for the right price.
Liverpool and Manchester United have been linked with the French defender.
While Leipzig chief Mintzlaff did not say when his club would consider a sale for Upamecano and their other star performer Marcel Sabitzer, he confirmed in an interview with Bild that sales would be considered.
"We have a squad that is also very broad in terms of quality," stated Mintzlaff.
“So we will also sell top performers again if it makes financial sense and we can absorb it from a sporting point of view.
"When I think of (Timo) Werner, (Matheus) Cunha, (Naby) Keita or (Diego) Demme, we've already made a lot of money and still made progress in terms of sport.
"Overall, we have invested a lot in our team, no question about that. But look: the current squad had a market value of less than 250 million when the individual players made their debut.
"And if we now take the current market value, we are at around €550million. You have to take this plus of over €300million into account when you talk about investments. We are creating value with our path."
