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.
The first advantage that Chelsea will get over Aubameyang is that Aubameyang is already used to the rhythm of the game in the EPL. The second advantage is that Aubameyang already knows the average team playing style in the EPL.
I think it's very important for Aubameyang to help a team that is Chelsea who are in need of a striker.
Facing several competitions, Thomas Tuchel must move again in the winter transfer window to look for players who are in the same position as the former Arsenal player to anticipate if Auba gets injured.
