Arsenal manager, Mikel Arteta, has wished Pierre-Emerick Aubameyang all the best at Chelsea.
The former Gunners captain completed a deadline-day move from Barcelona to the Blues.
Aubameyang was unveiled by Chelsea late on Thursday night after the Blues agreed to a £10.3m deal with Barca.
Barca only signed the 33-year-old in February after his contract at Arsenal was terminated.
Aubameyang spent four years at the Emirates, scoring 92 goals in 163 games.
Reacting to Aubameyang’s return to the Premier League, Arteta said: “I’m sure he’s made that decision because he wants to change again and find the best possible for his future, and we here wish him the best of luck.”
