1. Simon Moore 7
Made a rare start for the Blades in Henderson’s absence but didn’t make his first save until the 29th minute, an easy one from Martial. Beaten three times in seven minutes but couldn’t be blamed for any of those goals Photo: Simon Bellis
2. George Baldock 7
Looked like the only £50m-quality full-back on the pitch for the majority of the game, before Man United’s quickfire treble turned the game on its head Photo: Danny Lawson
3. Chris Basham 8
Came out on top in an early one-on-one against the pacy Rashford and flew into every tackle after that as if his career depended on it Photo: Nathan Stirk
4. Phil Jagielka 7
Another rare starter with Egan injured, Jagielka barely put a foot wrong until the visitors decided to show up Photo: Danny Lawson
