If Aubameyang isn't a crucial player for Chelsea, Chelsea management won't force them to sign Aubameyang on the last day of the transfer window. If you followed the issue on Chelsea squad, you must know that Chelsea was looking for a strong CF to be the replacement for Lukaku. Chelsea needs a pure CF to score more goals, Aubameyang is a perfect player to solve the crisis in Chelsea attacking line. Anyway, Havertz isn't a pure CF, so he has nothing to do with Aubameyang's position. Don't you understand that Havertz is an attacking midfielder?
