RB Leipzig insists Timo Werner won't leave on the cheap.
The Germany striker, 22, has agreed personal terms with Bayern Munich over a switch to the Allianz Arena.
The forward, monitored by a number of European clubs - including Liverpool , PSG, Barcelona and Real Madrid - has already decided on his future.
But RBL chief Ralf Rangnick warned: "A possible agreement is impossible for 2019 [right now].
"We would have to agree, and we are not.
"Nobody has approached us from Bayern."
