9. Mark Duffy 8
Not his best display first half but came alive in the second, capped by a superb curling strike to put the Blades ahead. Played like a man possessed, demanding the ball at every turn and ran himself into the ground Photo: Simon Bellis
10. David McGoldrick 9
The former Forest man showed his old club exactly what they missed by letting him go, with another superb display. Teased a red-card challenge out of Benalouane and deserved a goal of his own Photo: Lynne Cameron
11. Gary Madine 7
Another hard-working shift from the big striker who showed his quality with the ball at his feet on occasions, too. Substituted to a standing ovation in the second half Photo: Simon Bellis
12. SUBS: John Lundstram 7
Came on to shore United's midfield efforts up and did what was required of him, using the ball tidily on a couple of occasions Photo: Simon Bellis
