After letting Alexis Sanchez join Manchester United, Arsene Wenger is keen to fill the void by signing a world-class striker.
Express Sport understands negotiations are likely to drag on for Aubameyang, with £55million being demanded for the Gabon international.
Olivier Giroud is on Dortmund’s radar, and the Bundesliga outfit have supposedly made clear a move for the Frenchman is not linked to Aubameyang.
Gunners chief executive Ivan Gazidis was spotted in Dortmund along with head of recruitment Sven Mislintat as they try to thrash out a deal.
However, according to the Daily Mail, Aubameyang’s transfer has been slowed down with the club unwilling to sanction his exit until they have signed a replacement first.
The report suggests Arsenal remain confident of landing the 28-year-old.
When asked last week why Aubameyang could be sold, Dortmund’s sporting director Michael
Zorc said: “At some point you can’t tolerate it any more.
“I don’t know what’s going on inside his head.
“We had a very contentious discussion today. We’re not used to this behaviour from him.
“What is going on now is not to be tolerated by the club. It is clear, It cannot go on like this.
“I don’t know what is going through his mind. I don’t recognise him anymore.”
