Goals from Sander Berge and Jack Robinson put the Blades in command before former Swans man Oli McBurnie came off the bench to tap home a third late in the game.
Here’s how we rated the Blades’ players on another impressive afternoon at Bramall Lane ...
5. John Egan 7
Almost joined Robinson on the scoresheet with a bullet header with five minutes or so remaining that he thought was flying in, but Fisher in the away goal did well to push it away for a corner Photo: Mike Egerton
6. Jack Robinson 8
Nearly took the net off with his well-struck goal, showing good awareness and composure after Norwood's free-kick came back off the bar. Had a chance for a second when his volley hit the base of a post and bounced out and played his part in a melee later in the game after tumbling with Fulton Photo: Simon Bellis
7. Max Lowe 7
Another solid display down the left flank for Lowe, who was always looking to get forward and make things happen. Made way in injury time for Fleck to make his return from injury Photo: Jonathan Gawthorpe
8. Sander Berge 7.5
After rediscovering his goal touch in midweek, found the net for the second game in succession with a beautifully-composed finish into the bottom corner. Had some nice moments on the ball as he drove forward but doesn't quite look up to full speed yet in terms of fitness Photo: Andrew Yates
