According to agent Vincenzo Morabito, Dortmund rejected a 90 million euro offer from London's Arsenal for striker Pierre-Emerick Aubameyang this summer.
The Gabon national team member scored 39 goals last season, so it's no wonder he was linked with a move to one of the wealthier clubs.
Morabito, as a representative of Napoli, inquired about the striker's situation, having sold Gonzalo Higuain and looking for a replacement.
"Some time ago, I called Dortmund's sporting director Michael Zorc to discuss Aubameyang," the agent told Radio CRC. "But the answer was a categorical 'no'."
"I know that this summer, Arsenal offered 90 million euros for Aubameyang, but Dortmund didn't want to hear anything about it."
This season, Aubameyang is also performing excellently and has scored as many goals in 14 matches in all competitions.
