Mikel Arteta has accused his Arsenal players of lacking the standard required to win the Premier League after Saturday's 1-0 home defeat to West Ham United.
Jarrod Bowen's 44th-minute diving header was enough to secure a surprise win for the visitors at Emirates Stadium as Arsenal mustered just two shots on target in a subdued display.
The result leaves Arsenal eight points adrift of leaders Liverpool, who can extend that advantage into double figure with victory at Manchester City on Sunday.
Following injuries to Kai Havertz, Gabriel Jesus, Gabriel Martinelli and Bukayo Saka, the Gunners were without a recognised striker against West Ham with midfielder Mikel Merino called in as a makeshift alternative.
