Highly respected Sky Sports journalist Guillem Balague revealed the full details of this big money transfer on twitter earlier today.
Aubameyang moved to Dortmund from French side Saint Etienne in 2013. During his time at the Westfalenstadion he has blossomed into one of Europe’s top strikers, notching an impressive 98 goals in just 144 appearances.
Many Gunners would have been disappointed last week when the club lost Alexis Sanchez to bitter rivals Manchester United. However, having taken Armenian playmaker Henrikh Mkhitaryan as part of that deal, and with the club now closing out the transfer of superstar striker Aubameyang, maybe this wont be that bad a transfer window for Arsenal fans after all.
