Arsenal remain sweating on the fitness of their midfield general Thomas Partey, who faces a race to be fit in time to face Jurgen Klopp's Liverpool.
The Gunners travel to Anfield for Saturday's late kick-off, and remain in the dark as to whether key man Partey will be able to take to the field.
The 28-year-old missed the last match prior to the international break, against Watford, after complaining of a tight groin.
As a result he withdrew from duty with Ghana over the break, in order to work on his fitness and get closer to returning to match action.
