Sheffield United claimed a stunning win over Arsenal to move into the top half of the Premier League.
Lys Mousset marked his first start for the Blades with the decisive goal in the first half, turning in Jack O'Connell's knockdown from close range.
The victory was Sheffield United's biggest result since their return to the Premier League as they moved up to ninth, four points clear of the relegation zone.
Defeat for Arsenal, meanwhile, means they missed the chance to move back into the top four. They are fifth, two points behind Chelsea in fourth.
Sheffield United have certainly shown plenty of grit on their return to the Premier League and have been particularly impressive in not rolling over to sides in the top six.They battled from two goals down to draw 2-2 at Chelsea in August before pushing Liverpool close at the end of last month, only to be undone by a single goal from a mistake by Henderson.
