Borussia Dortmund sporting director Michael Zorc has insisted that winger Pierre-Emerick Aubameyang will not leave this summer.
The 26-year-old is a confirmed target for Internazionale with Arsenal also interested according to reports in England.
But Zorc says the winger is an important element ahead of next season.
"We rely heavily on Aubameyang - that is no secret," Zorc told Kicker.
"I've heard a lot about this [a transfer to Arsenal or Internazionale] but I can say very clearly that it is blocked for him.
"He is simply not for sale."
