Chelsea have completed the signing of Pierre-Emerick Aubameyang from Barcelona.

The striker joined Barca from Arsenal in January this year, but he has now returned to London in a deal worth £10.3m.

Aubameyang has signed a two-year contract with the Blues.

On becoming a Chelsea player, Aubameyang said: "I'm really happy. It's an honour to be part of this team and I can't wait to start.

"I have some unfinished business with the Premier League so it's good to be back and really exciting."

Chelsea chairman Todd Boehly said: "Pierre-Emerick is an elite striker with a proven track record in the Premier League and his arrival strengthens our squad, giving us new attacking options. We are thrilled to have Pierre-Emerick on board with us in the new era at Chelsea and we're really looking forward to working with him."

Aubameyang spent four years with Arsenal, where he scored 92 goals in 163 appearances.
