- Striker back in the Premier League
- Two-year contract signed
- Alonso moves in the opposite direction
WHAT HAPPENED? The Gabon international only moved to Camp Nou in January, after being frozen out at Emirates Stadium, but he has returned to London on a two-year contract. Marcos Alonso, meanwhile, is set to move in the opposite direction after the mutual termination of his contract with the Blues.
THE BIGGER PICTURE: While he has filled a wide attacking role on a regular basis across his career to date, Thomas Tuchel will be hoping that Aubameyang - who he has worked with before at Dortmund - can become the central striker they are crying out for. He previously hit 92 goals through 163 appearances for Arsenal.

WHAT NEXT FOR AUBAMEYANG: As a proven Premier League performer, the 33-year-old will want to hit the ground running at Chelsea – with the Blues next in action against West Ham on Saturday.
