Bayern Munich chief Karl-Heinz Rummenigge has left the door open to Niklas Sule leaving this summer.
The defender is being tracked by Chelsea and Manchester United with his contract now inside it's final 18 months.
Bayern have raised the prospect of a new deal, but Sule's demands are proving too steep.
Asked who will leave, Rummenigge said: "We'll see.
"David Alaba leaves and maybe one or two other defenders..."
