I think that the Aubameyang deal is beneficial for each side. Because Chelsea immediately needed to sign a striker before the end of the window. Otherwise a very tough season was waiting for them due to scoring problems. Aubameyang is one of the great choices available in the market. He is very familiar with the Premier League too so there wouldn't be any adaptation issue as well. Barcelona needed to get rid of some players to solve their registration problems in the La Liga also. Depay or Aubameyang was needed to leave and they reached their goal.
Correct me if I am wrong, but hadn't Barcelona registered all their new signings already after selling off some TV rights, or so I understand?
Any way, Aubameyang to Chelsea will really benefit Chelsea so much in terms of attack. The current forwards are not worthy of playing in a team like Chelsea.
They solved to the attacking issues with Aubameyang present.
The midfielder's will be highly held if they lost next against West Ham
They Chelsea needs an upgrade in midfield is that too hard to comprehend
