Aubameyang played very well with Barcelona last season. He did not perform in any match for a long time. Even then he was able to play well enough with Barcelona. And I guess he will be able to perform well with Chesley as well.
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 may strengthen Chelsea's forwards, but Chelsea's defense is also weak. In 5 matches they scored only 6 goals and conceded 8 goals. Hence, Chelsea management should take appropriate steps quickly to strengthen the defense as well. Otherwise, Chelsea should change their match strategy.
Chelsea must realize their weakness at defense line, that's why they sign Wesley Fofana. I assume Chelsea defense will be strong again with some new players. Their strategy will be more effective with new experienced and skilled players. Just wait for an improvement on Chelsea perfromance in the next few matches. Be calm!!
