Aubameyang was doing so well as an Arsenal player before his controversial move to Barcelona back in January though I supported Arteta's decision because as a leader you are expected to lead by example not giving other players the wrong impression and example to follow. He's currently doing well at Barcelona. With the club's decision to sell out players I hope he stays and helps the club.
Arteta had a big calculation by moving Aubameyang to Barca and it was proven because Arsenal's performance did not go down
moving to Chelsea is actually a way for aubameyang to help barca from the difficulties they are going through to registering kounde before transfer market close
barca currently has a surplus of good strikers while chelsea is in crisis for good strikers so if Aubameyang goes to chelsea, it will help 2 clubs
