Thibaut Courtois: Too rarely tested by United when they had 11 men, let alone when they were reduced to 10, but saved well from Marcus Rashford when the striker was through one-on-one - 7.
Cesar Azpilicueta: Positioning was typically sound but Chelsea's dominance of possession was such that, like Courtois, he was rarely needed - 6.
David Luiz: A composed presence on an intense evening. Often curbed his attacking instincts to allow Gary Cahill to go further forward - 7.
Gary Cahill: Forced a fine early save from David de Gea, but beaten by Rashford's footwork when Chelsea's last defender during the second half - 7.
Victor Moses: Often got the better of Ashley Young on the right wing but Chelsea's most regular success came more centrally or on the left - 6.
Marcos Alonso:. Provided a consistent attacking threat, and impressed with the ground covered in each half - 7.
N'Golo Kante: Overcame United's resolute defending by creating space in midfield before scoring only his second goal for the club with a fine finish. His first also came against United at Stamford Bridge - 9.
Nemanja Matic: Worked to negate Marouane Fellaini's physicality during the second half as Kante dictated Chelsea's tempo - 7.
Willian: Chelsea's movement is not as fluid when he plays instead of Pedro, but his superior defensive contribution justified his inclusion on an evening when United were expected to offer more - 6.
Diego Costa: Provided his usual physical threat without testing the visiting goalkeeper in the manner expected of him. Headed wide when well-placed in second half - 7.
Eden Hazard: Chelsea's most influential performer. His creativity and intent regularly created space in a crowded midfield, and led to the two fouls that ensured Ander Herrera was sent off - 9.
Cesc Fabregas (for Willian, 81mins): An exceptional option to have off the substitutes' bench. Ensured Chelsea continued to dominate and tested De Gea late on - 6.
Kurt Zouma (for Moses, 89mins): A welcome first-team appearance after a period undermined by injury - 5.
Michy Batshuayi (for Costa, 90+4mins): Brought on to run the clock down at far too late a stage to have any impact of note - 5.
David de Gea: The tone for a busy evening was set by impressive early saves from both Cahill's and Hazard's shots. Without him Chelsea would have won by a far greater margin - 8.
Phil Jones: United's best defender throughout the second half as they fought to resist Chelsea's obvious dominance. On this form can become a significant asset in United's defence - 8.
Chris Smalling: A largely sound performance but again gave the impression he lacks the confidence to do more on an evening where United were regularly under pressure - 7.
Marcos Rojo: Risked conceding a penalty with a second-half challenge on Diego Costa, who kept him busy throughout - 6.
Antonio Valencia: One of the few United players who appears capable of holding down a first-team place at Chelsea. Typically energetic - 7.
Matteo Darmian: Struggled against Willian, Hazard and Moses during the second half. Surely an inferior option to Luke Shaw or Daley Blind - 5.
Ander Herrera: Struggled, as United did, amid Chelsea's movement in the attacking half, and left his team with 10 men after being sent off following bookings for two fouls on Hazard - 5.
Paul Pogba: Began with promise in a system not suited to his strengths, but after Herrera's red card struggled as Kante increasingly imposed himself - 5.
Henrikh Mkhitaryan: Substituted towards the end of the first half when Jose Mourinho brought on Marouane Fellaini after Herrera's red card. Had had little opportunity to exert any sort of influence - 5.
Ashley Young: Increasingly appears fortunate to be a squad player at United, and struggled more and more as the game progressed - 5.
Marcus Rashford: Played with both energy and desire, but United's already limited attacking options were further reduced when they were left with 10 men - 6.
Marouane Fellaini (for Mkhitaryan, 37mins): Introduced to provide a physical presence in midfield. Did that, but little else - 5.
Jesse Lingard (for Young, 81mins): Provided respite to the struggling Young but made little impact. Changing the game was beyond almost anyone by that point - 5.
