Pierre-Emerick Aubameyang's below par performance on Tuesday night against Arsenal has drawn the irate eye of former Chelsea star Craig Burley.
The Blues were handed a further blow in what has been a nightmare season by their bitter rivals, who inflicted a 3-1 defeat over them at the Emirates.
Martin Odegaard struck twice before a third from Gabriel Jesus put the hosts 3-0 before half-time, and although Noni Madueke pulled one back in the second half, Frank Lampard's side suffered a 14th loss of the campaign.
Aubameyang was making his return to the club were he was once captain, but failed to have the desired impact on the game in what was a largely anonymous performance for Chelsea.
