David Moyes branded West Ham's 6-0 humiliation by Arsenal as the worst defensive display since his return to the club as thousands of fans left at half-time.
The Gunners were 4-0 up by the interval courtesy of goals from William Saliba, Bukayo Saka, Gabriel and Leandro Trossard.
And further goals after half-time from Saka and Declan Rice compounded the home side's misery.
It leaves Moyes without a win in five league games having previously beaten Arsenal twice this season - 3-1 in the Carabao Cup and 2-0 in the league.
