Atletico Madrid chief Andrea Berta insists Lucas Hernandez won't be leaving next month.
The defender is a target for Bayern Munich.
And Marca claimed that the German club would pay the defender's €80m release clause next month.
But Berta says: "I can't say anything, you will have to ask [Karl-Heinz] Rummenigge [about Bayern's interest].
"Lucas told me he wants to stay with Atletico. Lucas is a very good player. He's an important player."
