Arsene Wenger appeared to drop a Pierre-Emerick Aubameyang transfer hint while starring in a video alongside an Arsenal fan.
The Gunners are keen on signing the Gabon international before the January transfer window slams shut on Wednesday.
Aubameyang has been earmarked as a replacement for Alexis Sanchez, who left north London for Manchester United earlier this month.
Arsenal remain confident of securing the 28-year-old's signature, despite fearing the transfer will go right down to the wire.
And they're willing to offer the striker - who is desperate to move to the Emirates - a three-and-a-half year deal worth £180,000-a-week.
Dortmund have told Arsenal they are ready to sell the striker for £60million, but the Gunners have so far rejected two bids that have fallen short of this figure.
Aubameyang featured for Dortmund in their 2-2 draw with Freiburg on Saturday, but this hasn't deterred the Gunners in the race for his siganture.
Wenger took some time out of his busy schedule to visit the Lee Valley Athletics centre to watch the London Indoor Games on Sunday.
He bumped into an Arsenal fan at the event who hinted to the Aubameyang transfer without explicitly asking the Gunners boss.
The Frenchman failed to reply directly in the clip, but did produce a wry smile as if to say the deal is close to completion.
