RB Leipzig chief Oliver Mintzlaff cannot rule out the sale of Timo Werner in January.
The Germany international is being linked with Real Madrid, Chelsea and Bayern Munich.
Asked about Werner's situation, Mintzlaff said: "I could now answer with empty phrases, then it will be tedious for your readers. And if I don't say anything, it's also unsatisfactory.
"I can only say that basically nothing is excluded."
He added: "If we can no longer offer a player the platform on which to perform, we have to discuss it fairly. So far, we have always been a platform on which there was no reason for Timo Werner to leave."
