RB Leipzig CEO Oliver Mintzlaff has opened the door for Dayot Upamecano to move on by insisting that the Bundesliga side will always listen to offers for their star players.
The France international is believed to have a release clause in his current deal, but Mintzlaff has suggested that the 22-year-old could leave for less if the money is right.
"We have a squad that is very broad in terms of quality. So we will sell top performers again if it makes financial sense and we can cope with it from a sporting point of view," Mintzlaff told Bild.
"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 the sporting side.
"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 €250m (£225m) when the individual players made their debut.
"And if we now take the current market value, we are at around €550m (£496m). You have to take this plus of over €300m (£270m) into account when you talk about investments. We are creating value with our path."
Upamecano has scored once in 20 appearances for Leipzig during the 2020-21 campaign.
