RB Leipzig sports chief Oliver Mintzlaff cannot guarantee keeping hold of Dayot Upamecano.
The defender, with a contract to 2023, is being linked with a move away this summer, as Manchester United, Liverpool and Bayern Munich all circle.
Mintzlaff is well across the transfer speculation and admits everything is wide open.
“Everything is open and I would be happy if he stayed with us," he said.
Upamecano's contract carries a €42m which will be triggered in 2021.
