Im not sure if aubameyang become a crucial part of chelsea plan , he might signed as additional due how the price bargained with alonso swap deal and a striker needed besides the false 9 plan with havertz almost irreplaceable, he might will have a rest time now lol , however i wish auba could follow ashley cole, giroud and gallas who win nothing at arsenal but win a lot of trophies at chelsea.
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?

Don't you understand that kai havertz scored the winning goal in champions league final didn't make him what so called 'PUR3' STR1k3R ? Despite his genuine position are an attacking midfielder ?
Chelsea did make auba transfer in panic buying , the club could sign a more long-term striker than him.
Havertz will remain become chelsea first choice while auba come second as a backup plan.
