Wayne Rooney scored twice as leaders Manchester United came from behind to beat Sheffield United.
The Blades took a surprise lead when Keith Gillespie headed in Derek Geary's cross against his former club.
But Rooney hauled the visitors level when he coolly found the net from a Gary Neville cross.
Rooney won it on 75 minutes when he drilled in Patrice Evra's cross before Cristiano Ronaldo hit the crossbar and then blazed over from just three yards.
