Pierre-Emerick Aubameyang joined Chelsea on deadline day in the summer transfer window after leaving Arsenal earlier this year.
The 33-year-old left the Emirates Stadium following after a series of disciplinary issues which resulted in him losing the Gunners club captaincy role. Aubameyang secured a free transfer to Barcelona in the January transfer window after his relationship with Mikel Arteta broke down.
The Gabonese striker returned to the Premier League after completing a deadline day move to the Blues, reuniting with Thomas Tuchel before the German was sacked just days later. Arsenal are currently leading the way at the top of the Premier League and will be looking to maintain their two point gap above Manchester City with a win against Chelsea at Stamford Bridge.
