The 28-year-old is set to become the Gunners' record signing just five months after they set that mark to add Alexandre Lacazette
Arsenal are on the verge of signing Pierre-Emerick Aubameyang from Borussia Dortmund after the clubs agreed a £60 million fee in principle for the Gabon international.
Aubameyang, 28, has been subject of negotiations between the Gunners and Dortmund for several weeks, with Arsenal refusing to meet the Bundesliga side's £70m asking price.
The striker, who scored 31 league goals last season, was left out of two consecutive games for Dortmund after missing a team meeting, with head coach Peter Stoger accusing the frontman of not being focused.
