The Blades actually started reasonably well, but soon lost heart when they realised what they were up against, and the second half was far too easy for Mikel Arteta's men./
Chief football writer Stuart Rayner looks back at how the individuals performed.
Aaron Ramsdale – got lucky with a clearance against Alexandre Lacazette and his save teed up Arsenal s second 6
Ethan Ampadu – gave away a dangerous free-kick on the edge of the area in the second half 6
John Egan – had a defiant volley at the end of the first half 6
Enda Stevens – started in a back three, finished wide of a back four 6
George Baldock – Arsenal had Granit Xhaka out of position at left-back but Baldock was never able to test him 6
John Lundstram – his poor pass set up the second goal 4
Oliver Norwood – worked hard, but did not play well 5
John Fleck – part of an anonymous midfield 5
Ben Osborn – better at left wing-back than in the hole, but the Blades' best player 7
David McGoldrick – had a couple of shots early in each half but both off target 6
Oli Burke – pressed energetically early on but it came to nothing 6
Rhian Brewster (for Burke, 64) – had little effect, but any striker would have struggled 5
Oli McBurnie (for McGoldrick, 64) – went off injured after less than 20 minutes on 5
Lys Mousset (for McBurnie, 83) – had a late shot wide 6.
