Yep, Aubameyang became one of the Barcelona players who can perform well last season. Sadly, Barcelona signed Lewandowski and forget his contribution last season, then Aubameyang lost his position as the main CF in Barcelona lineup. It is another sad story in Aubameyang career, but I am sure he doesn't lose his spirit to play at his best form in a new club (Cheslea). There is no problem with Aubameyang skills, he is still a sharp or productive striker. So, he should have no obstacles to perform well with Chelsea team.
Aubameyang helped Barcelona last season can finish on second position standing but arriving Lewandowski make him difficult to get regular position what ever as central forward or Xavi Hernandez can't give space for him as winger position. Many alternative with other winger like Ousmane Dembélé and Ansu Fati have consistent performance in this season can't give more minutes playing for Aubameyang.
No doubt with Aubameyang skill, he still talented forward and he has adapt well with Primer League after success before on Arsenal. Nowadays Aubameyang can open new challenge with Chelsea and how to make fans expected with his contribution for scoring goals on every games because Chelsea have losing two attacking player like Timo Warner and Lukaku.
