It was a performance that United boss Dan O'Hearne described as a good as he's seen so far in his time as first team manager.
United went into the Women's FA Cup third qualifying round tie as underdogs against a side from one level higher and that has a good track record against United from their league days two seasons ago. But another focused and professional performance from the Blades gained a deserved victory.
Chester-le-Street set the early pace but United withstood the pressure and slowly turned things around to look more and more comfortable in control. United went close when winger Shannon Smith elected to go for goal although Kim Brown was in support but the goal was not far away coming.
On 32 minutes Brown picked the ball up and showed her confidence by lobbing the goalkeeper from 25 yards out to put United ahead with her ninth goal of the season already.
The hosts did press in search of an equaliser but the entire United defence were outstanding in restricting real chances to a minimum. United nearly had a second in the second half when in a scramble the ball came off a defender and onto a post.
Around the hour mark Jorden Spurr, who was probably United`s player of the match with her passing in midfield, picked up a clearance and curled a great shot a fraction wide. The game became a bit more of a hard fought battle and the closest the home team came to scoring was in the last minute. United 'keeper Kirsty Johnson initially saving and the follow up finish was ruled offside.
So United were delighted to win 1-0 and have drawn Merseyrail Bootle at home in the next round. The win makes United`s record this season six wins and a draw from the seven games played and three consecutive clean sheets.
Blades: Johnson, Hartley, Neary, Cawthorn, Hopkinson, Smith (Darbyshire), Ruddach, Spurr, Bell, Celi (Carroll), Brown.
