Borussia Dortmund sporting director Michael Zorc has made it vehemently clear that the club has no plans to sell Pierre-Emerick Aubameyang.
The 26-year-old Gabon striker is a strong target for Arsenal after scoring 26 goals in the Bundesliga last season but Dortmund insist they have no plans to offload their star anytime soon.
"We rely heavily on Aubameyang - that is no secret," Zorc told German magazine Kicker.
"I've heard a lot about this (a transfer to Arsenal) but I can say very clearly that it is blocked for him. He is simply not for sale."
Arsenal will reportedly make a return bid of £30million for Aubameyang who has three years to run on his current deal with Dortmund.
