Ruben Loftus-Cheek - (On for Barkley 78') NA: Came on a minute after third goal with game over. Reuters
SHEFFIELD UNITED RATINGS: Dean Henderson 7: Not put under much pressure, to be fair, but whatever he did, he did well. One good save from James' speculative strike in first half, another header hit straight at him from Giroud after the break. Dominated the penalty area, unlike his Chelsea counterpart. Getty
George Baldock - 7: Right-back was booked after just two minutes for foul on Pulisic, but held his nerve navigating red-card tightrope for rest of match. His ball into box helped set up Blades' first goal. AFP
Jack O'Connell - 7: Vital touch that sent an Azpilicueta shot wide in second half. PA
John Egan - 8: Part of a fantastic defensive performance and left the dangerous Abraham hunting for scraps. AFP
Chris Basham - 8: Blades were so well drilled at the back with Basham playing his part. AFP
Enda Stevens - 7: Played lovely one-two with O'Connell down the left before inch-perfect cross found McBurnie for the second goal. Blazed chance to make it 4-0 over the bar. AP
Oliver Norwood - 7: Blades captain is such an important cog his team's organisation. Full of running. AP
Ben Osborn - 7: Stabbed a good chance over the bar early on after a poor Kepa punch. Another who never stopped for 90 minutes, playing his part in defence and attack. Reuters
Sander Berge - 6: Midfielder worked very hard defensively from midfield without the impact in attack that he is capable of. AFP
Oliver McBurnie - 8: Brilliant bullet header from the Scot to put the Blades 2-0 up. Worked himself into the ground up front before making way just after the hour mark. Getty
David McGoldrick - 8: Showed great reactions to score his first Premier League goal after Kepa saved from McBurnie. Similar instincts to grab his second after Rudiger's blunder. Striker produced some lovely footwork at times and put in a fantastic shift. Reuters
SUBS: Lys Mousset (On for McBurnie 63') 7: Played part in third goal and will be disappointed not have scored himself when he chipped wide after great work from McGoldrick helped put him clean through. Getty
John Lundstram - (On for Berge 63') 6: Slotted straight into the midfield with no problems. EPA
Phil Jagielka - (On for Basham 68') 6: Rare appearance for the veteran defender. AP
CHELSEA RATINGS: Kepa Arrizabalaga - 5: Continues to be weak link for Chelsea. Could only parry deflected shot into path of McGoldrick for opening goal. Very unconvincing on crosses and fails to command area. PA
Reece James - 6: Started well and his early cross provided Pulisic with early chance to take the lead but the right-back was taken apart by Stephens' movement for second goal. Forced decent save out of Henderson just before the break. Getty
Kurt Zouma - 5: Was beaten to the ball far too easily when McBurnie headed home the second. PA
Andreas Christensen - 5: Picked an early knock and never looked comfortable. Hooked at half-time. Reuters
Cesar Azpilicueta - 6: Captain couldn't lift his team on a bad day for Chelsea. Saw one second-half chance deflected wide. Reuters
Jorginho - 6: Italian back in team after spell on bench and his usual neat and tidy self but was caught in possession a few times as Chelsea capitulated. Getty
Mason Mount - 5: Buzzed around while contributing very little. Taken off at half time. PA
Ross Barkley - 5: Midfielder went missing when Chelsea needed him. PA
Willian - 5: Should have done more to assist James down the right for the Blades' second. Disappointing show. AFP
Christian Pulisic - 6: Headed first-half chance over the bar. Flashes of his undoubted talent but the American came up against an incredibly well organised Blades defence. Reuters
Tammy Abraham - 5: Just 13 touches in the entire first half for the striker. Had a couple of chances in second half but lacked the killer touch on both occasions. AFP
SUBS: Marcos Alonso - (On for Alonso 45') 6: Brought on to give Chelsea more width down the left as Lampard changed formation in second half with little effect. AFP
Antonio Rudiger - (On for Christensen 45') 5: Awful error when he got his feet in right old muddle to gift McGoldrick his second goal. AFP
Olivier Giroud - (On for Pulisic 66') 6: Difficult chance with first touch but could only volley. AP
Callum Hudson-Odoi - (On for James 75') 6: No chance to make any impact. Getty
