Marcus Rashford scored twice as Manchester United earned a 10th straight away league win, coming from behind to claim a 3-2 victory at Sheffield United.
The home side took the lead on five minutes when David McGoldrick tapped in after Sheff Utd had taken advantage of hesitation from their former on-loan goalkeeper Dean Henderson.
John Fleck shot narrowly wide soon after before Rashford superbly controlled Victor Lindelof's long pass and fired in to equalise on 26 minutes.
The visitors went in front seven minutes later with Anthony Martial prodding home after being found by Paul Pogba's deft pass.
Rashford finished a flowing counter-attack involving Pogba, Bruno Fernandes and Martial to make the score 3-1 in the 51st minute.
McGoldrick headed in his second with three minutes remaining before the hosts were denied an equaliser when Henderson saved from substitute Lys Mousset.
The victory moves Man Utd up to sixth on 23 points, while Sheff Utd remain bottom of the table with one point.
