Mikel Arteta has admitted that his players are focused on how they can prevent Pierre-Emerick Aubameyang from scoring as Arsenal visit Stamford Bridge.
Aubameyang joined Chelsea from Barcelona in August, a little over seven months after he had completed an acrimonious departure away from the north London side which included a high-profile falling out with Arteta.
The Gabonese attacker faces Arsenal for the first time since leaving the club this afternoon and his role in the fixture has been much-discussed after featuring in a controversial BT Sport advert ahead of the game.
