Chris Wilder has a few selection headaches as the Blades look to build on two clean sheets to start the season, as he looks to coax a little bit more attacking quality out of his side from Saturday’s goalless draw with Birmingham City.
Mark McGuinness has done little wrong since being handed an unexpected run at centre-half, while Sydie Peck has also taken his opportunity in midfield. There is competition for places further forward, too, with Romelle Donovan, Callum O'Hare, Patrick Bamford and Tyrese Campbell all vying to make an impact.
With United still waiting on reinforcements before the transfer deadline, Wilder's current options will form the basis of his selection once again. Here is how we expect the Blades to line up at Swansea - have we got it just about right or would you do anything differently?

A great battle down the left flank between McCallum and Burrows but McCallum is in the side and could keep his place | The Star/Sport Image
6. Sydie Peck
United's midfield will face a tough test against a side that love to keep hold of the ball and so Peck's tenacity and composure could be key | The Star/Sport Image
7. Joe Rothwell
There's some great competition in there from Arblaster and Riedewald, with Phillips still to come back as well, but Rothwell was good last weekend and his ability to retain the ball could be key | The Star/Sport Image
8. Romelle Donovan
The summer arrival has already shown glimpses of his ability and has the directness and energy Wilder is looking for on the wings | The Star/Sport Image
