A long away trip to mid-table Kettering Town saw the Blades put in a below par performance but register another win to keep up the unbeaten start.
United couldn't find their usual passing game and were struggling to get a foothold in the game until a strike from Jen Pearson was tamely helped into the goal by the home 'keeper after 17 minutes. The Bladettes then settled down and had some quality passages of play to gain some confidence from.
A well-worked corner from Shannon Smith and Kim Brown saw the latter put in a pin-point cross for captain Neary to arrive unmarked at the back post with a diving header after 43 minutes.
Play was halted shortly after when a serious-looking injury to central defender Molly Cawthorn resulted in her been forced off, with Celi replacing her and the team being reshuffled.
Leading by two at the break, United were slightly better in the second half and Celi duly dispatched a shot from the edge of the area to put the Bladettes in total control after 70 minutes.
Two strikes against the woodwork saw the visitors looking for a fourth which arrived in the final minute when Celi played the ball into Brown's path for an easy tap in.
Blades: Johnson, Hopkinson, Cawthorn (Celi), Neary, Hartley, Pearson, Spurr (Hickerman), Ruddach, Smith (Wainwright), Brown, Carroll.
