David de Gea
Had next to nothing to do but was noticeably louder than at Tottenham. Kept his sixth clean sheet in the last eight. 6
Aaron Wan-Bissaka
Was present if unthreatening in attacks until his drilled cross was finished by Anthony Martial for another assist. 7
Victor Lindelof
Much more comfortable against Sheffield United's front two than he was in the reverse fixture. Rarely troubled. 7
Harry Maguire
Read the game well against his former side and made himself heard by rollocking Luke Shaw for a moment of doziness. 7
Luke Shaw
Purposeful, despite getting a wake-up call from Maguire. Got forward enough times to push Marcus Rashford infield. 6
Nemanja Matic
A roaring success on his return to the line-up. Matic tied things together in the holding role and was adventurous with his passing. 8
Paul Pogba
Picked up from where he left off at Tottenham. Pogba was athletic and creative in a more fluid United midfield. 8
Bruno Fernandes
Demanding of teammates in the first minute, Fernandes was overshadowed by Pogba on this occasion but still a creative presence. 7
Mason Greenwood
Deserved to start and began brightly but was not as involved in the United attacks as Martial and Rashford. Had attempts at goal. 6
Marcus Rashford
Found Martial with a low cross for the first but squandered good chances. Erratic again after a poor performance at Tottenham but created the third. 6
Anthony Martial
Scored two instinctive goals in a classic poacher's performance before he scored a classy third for a hat-trick. 9
Subs
Odion Ighalo
Another impressive cameo but should have scored. 6
Juan Mata
Another run around. 6
Andreas Pereira
Got minutes. 6
Daniel James
Stretched his legs. 6
Scott McTominay
More minutes. 6
