It was a frustrating evening at Emirates Stadium on Thursday as we were beaten 2-0 by West Ham United.
The visitors took the lead in the first half when Tomas Soucek fired home from close range with their first shot on target.
We continued to push forward in search of sparking a comeback, but former Gunner Dinos Mavropanos made it two shortly after the restart.
David Raya then denied Said Benrahma from the penalty spot deep into stoppage time.
