Arsenal scored two quick-fire team goals to extend Sheffield United’s point-less start to the Premier League season – although the Blades did manage their first goal.
The Gunners did not really get going until the 60th minute when Bukayo Saka celebrated his first England call-up with a header from Hector Bellerin’s cross.
Three minutes later they doubled their lead with Nicolas Pepe’s good run and finish into the bottom corner – finishing off a move with 19 passes.
They looked completely in control until David McGoldrick curled home the Blades’ first league goal of the season.
But it was not enough to affect the outcome and United have now lost seven consecutive top-flight games for the first time since 1975.
Mikel Arteta’s Arsenal move onto six points from three games, having lost 3-1 to champions Liverpool last Monday.
Next, Arsenal visit Manchester City in the league next Saturday, while Sheffield United host fellow strugglers Fulham same day.
