Aubameyang has less promising stats in the English league, only one season at a perfect level, after that he didn't stand out anymore and couldn't contribute anything to Arsenal before moving to Spain, which I see the English league is different, so it's difficult to adapt in the game plan , although we know Chelsea need a striker to help them this season, but it doesn't seem wrong to give Aubameyang one more chance at Chelsea, to prove his quality going forward.
I think the Chelsea coach also knows that so Thomas Tuchel dared to make the move by bringing Aubameyang to Chelsea to be coached differently so that he could prove his true quality to Aubameyang and that is a step that is not wrong because Chelsea are currently in dire need of a player like Aubameyang to add team performance in the Premier League. I believe Aubameyang is still able to adapt quickly in the Premier League this season.
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. 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.
