Pierre-Emerick Aubameyang is at Arsenal's training ground as the Gabonese striker closes in on a move from Borussia Dortmund.
The Gabonese striker jetted into Luton Airport on Tuesday as he bids to secure his transfer to the Gunners.
Aubameyang is set to move for a fee in the region of £60million as Arsenal look to replace the goals lost by selling Alexis Sanchez to Manchester United.
It could see Olivier Giroud head for the exit with Chelsea keen on the Frenchman, subsequently Michy Batshuayi could then join Dortmund.
Aubameyang will earn £180,000-a-week at Arsenal should the deal go through before tomorrow night's deadline.
He was pictured arriving at the airport at midday on Tuesday before catching a flight to London, where he landed around 2pm.
The forward will thrash out personal terms and undergo a medical but Arsenal are expecting negotiations to drag into the final day of the window.
Dortmund will not sanction the deal until they have a replacement.
Their No1 target now is Michy Batshuayi but Chelsea will not let him go unless they get Olivier Giroud from Arsenal.
Arsenal do not want to do business with a direct rival but may be forced into doing a deal to get the Aubameyang transfer over the line.
Dortmund have until February 2 to complete a deal for his replacement with the German window open until Friday.
Arsenal fans have been growing increasingly excited about Aubameyang's arrival with the striker seen as a replacement for Alexis Sanchez, who joined Manchester United earlier this month.
