#4 Pierre-Emerick Aubameyang
Aubameyang hasn’t had the best start to this season. He has failed to open his account three matches into the league and has missed few chances which should have been converted. However, those who know him, know better than to underestimate him. Aubameyang is one of the best strikers in the world. Insane pace and agility make him a constant threat whenever he is on the field.
Aubameyang joined Arsenal this January. A poor form last season could easily be justified as it would have been difficult for a new team in a new league. The only problem with that reasoning is that Aubameyang didn't have a poor season at Arsenal. He had a phenomenal season, with 10 goals and 4 assists in only 13 matches. That’s incredible for a new team, that too mid-season.
Arsenal’s slow start can be excused due to a new manager. However, Unai Emery has shown his teams pick up in performance as the season progresses (Three consecutive Europa Leagues with Sevilla). If that happens with Arsenal, you know who will be the main man in the Arsenal attack, and potentially the top scorer this season.
