Arsenal face a second consecutive London Derby when they play West Ham on Saturday.
The Gunners are set to come up against Jack Wilshere for the first time since he left Arsenal for the Hammers last month, with the Englishman revealing that he won't celebrate if he scores against his old club.
Unai Emery will pit his wits against Manuel Pellegrini once again after 10 previous meetings in La Liga, where the Spaniard won three, drew three and lost four.
Arsenal injuries
Left-back Sead Kolasinac is out for eight to ten weeks with a knee injury while Ainsley Maitland-Niles has suffered a fracture in his left leg and will be out for six to eight weeks.
