Premier League giants Arsenal have finally confirmed the signing of Gabonese striker Pierre-Emerick Aubameyang from German club Borussia Dortmund. The big African striker has been linked with a move to the Emirates all month and the club have now confirmed his capture on Wednesday afternoon, January 31. He completed a medical on Wednesday morning, January 31 and agreed personal terms with the club with his wages set to be worth £180,000-a-week. Aubameyang's move is now likely to allow Frenchman Olivier Giroud to complete his move to Premier League rivals Chelsea. Pierre-Emerick Aubameyang is expected to give Frenchman Alexandre Lacazette a serious competition in the first team at the Emirates Stadium. The Gabonese star is en-route to the UK to complete his £58m move to Arsenal, and he has been pictured at the Gunners' London Colney training base.
