Two goals from Marcus Rashford and a strike by Anthony Martial gave Manchester United a nervy win at Sheffield Utd.
Manchester dominated much of the game but fell behind when keeper Dean Henderson, playing against his former club, made a mess of a clearance which allowed David McGoldrick to tap in after just five minutes.
Rashford levelled scores twenty minutes later and Martial put Utd in front just past the half hour.
Shortly after the restart Rashford put Utd 3-1 up and Utd looked to be cruising right until
McGoldrick grabbed his second with minutes remaining.
A nervy final few minutes as Utd saw out the match and moved up to sixth in the table.
