Borussia Dortmund coach Thomas Tuchel has warned Arsenal off Matthias Ginter.
The Gunners were linked with the defender last week.
But Tuchel said: "With Ginter, I think everything is said. German clubs wanted to sign him and now English clubs want to sign him.
"I don't know if everything is true or it is just rumours but we made our point clear - Matthias is our player and stays our player."
