Boos rang around Old Trafford when Mathias Jensen put the Bees in front as United were staring down the barrel of a third consecutive defeat.
But Scott McTominay rescued the points for the Red Devils by scoring a stoppage-time double after coming off the bench.
And with the wind in their sails, Erik ten Hag's side will be expected to brush aside the Blades who go into this match off the back of a 3-1 defeat to Fulham.
Furthermore, the hosts are rock bottom of the league having just secured one point in their first eight games.
