Six months after his last league start for Chelsea against his former side ended in ignominy, history repeated itself for Pierre-Emerick Aubameyang on Tuesday night.
Aubameyang spent four years at Arsenal after being signed by Arsene Wenger and quickly established himself as one of the club's most influential players. However, Aubameyang's stay in north London turned sour under Mikel Arteta, who offloaded the Gabon international following a string of disciplinary issues.
Since returning to the Premier League, the 33-year-old has been a peripheral figure in a Chelsea side that have lurched from one crisis to the next and are currently languishing in the bottom half of the table - and just to rub salt in Aubameyang's wounds, Arsenal have flourished without him.
