#3 Pierre-Emerick Aubameyang

As a teenager, Pierre-Emerick Aubameyang joined AC Milan as a trainee. Despite being a part of the setup for five years, he didn't play a single game for the Rossoneri.
According to his peers and the hierarchy, he lacked technical quality. After an array of loan spells, the Gabon international settled at Saint-Etienne, before being snapped up by Borussia Dortmund, who turned him into a world-class act and arguably, one of the most clinical center forwards in Europe.
In just 213 appearances for the Bundesliga giants, he struck a mammoth 143 goals. After a controversy, Aubameyang was forced to leave and then started the Arsenal chapter.
He has starred for the Gunners so far, having netted 24 goals in just 37 appearances. At the moment, he is unstoppable, so much that even Harry Kane and Mohamed Salah are trying to match-up with him in the goalscoring charts.
