Arsenal 2-1 Sheffield United
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.
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 2-0 to champions Liverpool last Monday.
