History is pretty good if Arsenal players come to Chelsea. If you remember from Anelka to Giroud they came and won the title. Indeed Aubameyang is a little different he has to go to Barcelona before going to Chelsea.
Age-wise he is indeed old, but he became Barcelona's saviour to return to the top flight last season. The EPL has been friendly with him, I think he didn't take long for the adjustment. But I'm a little worried about whether this is Tuchel's panic because they played poorly at the beginning of the league and the transfer season that was about to be over.
Actually, in the current situation, Aubameyang's presence will definitely make Chelsea better because every time he plays he clearly gives a good performance.
Dortmund, Arsenal and Barcelona already feel that he is one of the strikers who can be relied on.
Now Chelsea are going through a tough time and it would be great if he could do some magic for Chelsea.
