For all the improvements
Arsenal have made under Mikel Arteta, their inability to see a game out remains chronic. They lost a lead here for the third time in his six-game tenure, continuing a theme that has dogged a miserable
Premier League campaign and makes a mid-table finish increasingly likely.

A goal close to half-time by Gabriel Martinelli, the brilliant 18-year-old who stood in ably for suspended captain, Pierre-Emerick Aubameyang, looked like being sufficient to win but John Fleck’s superbly taken equaliser, lashed in seven minutes from time, left Arteta frustrated again and provided fresh evidence of the redoubtable quality Chris Wilder has instilled in Sheffield United.
