But who caught the eye for the Blades? Our man Danny Hall offers his player ratings from the game.
1. George Baldock 7
Signalled his intent in this game early on with a thunderous challenge on Emerson and kept up that level of passion throughout. Mason Mount barely had a kick Photo: John Walton
2. Chris Basham 7
Almost set up an equaliser for Robinson with a superb cross and prevented Mount putting Chelsea 3-0 up in the first half with a critical last-gasp block. Replaced by Osborn late in the game Photo: Richard Sellers
3. Jack O'Connell 7
Got tangled up with Egan a couple of times but got across superbly to block a pass for the breaking Willian, who was racing through on goal. Superb cross almost set up Robinson again Photo: James Wilson
4. Enda Stevens 9
Set up Robinson's goal with a superb run down the left, less than a minute into the second half, and dealt well with very lively Pulisic down Chelsea's right. Belongs at this level Photo: Mike Egerton
