Pierre-Emerick Aubameyang's broad smile is unmistakable – and it has been seen often during the forward's early weeks as a Chelsea player.
Signed from Barcelona on transfer deadline day in a deal worth around £14million, Aubameyang was viewed as the missing piece of the puzzle for Thomas Tuchel, the player that would transform Chelsea from a somewhat stagnant possession-based side under the German to an effective attacking team.
The two had worked together at Borussia Dortmund and remained close. Yet one training session and 59 minutes of match action were all they shared at Stamford Bridge. Less than a week after Aubameyang arrived in west London, news came that Tuchel had parted ways with Chelsea.
