United's U23 returned to winning ways in the Professional Development League with a deserved victory at Gresty Road on Monday evening.
A first-half brace from Jake Wright, in addition to a goal from Louis Reed cancelled out Daniel Udoh's opener for the Alex, before David Brooks got on the scoresheet in the second period to ensure Callum Ainley's stoppage-time strike was nothing more than a consolation for the hosts.
Defender James Wilson, on his return from injury, captained the side and completed an hour against the Railwaymen, with the Blades also having the luxury of missing a penalty, with Dave Richards denying Ben Whiteman in the first-half.
Striker UDOH had already missed an excellent opportunity to opening the scoring, prior to rifling past Long in the 11th minute, but from there after it was pretty much one-way traffic.
Six minutes after going behind the Blades levelled. A long, high ball forward saw Richards misjudge the bounce and WRIGHT nipped in to head home into the unguarded net.
In the 23rd minute, United went in front and it was the ever-dangerous WRIGHT again, this time finishing well having been played through on goal.
Despite bossing the game, United need a helping hand from Richards, who had previously saved Whiteman's penalty, to get a third on the stroke of half-time. Bennett did well on the right before cutting back for REED to shoot at goal and his tame effort squirmed under the body of the home goalkeeper.
The Blades continued to have the upper hand at the beginning of the second with Reed having a couple of opportunities, at the other end, Long was alert to deny Ainley.
With 16 minutes remaining three became four, with Richards again at fault. He rushed from his goal to try and snuff out the danger only for BROOKS to beat him to the ball and stab home.
To Crewe credit they kept going until the final whistle and got goal for their efforts, as AINLEY finished off following good work by Kirk down the right-wing. But it was the visitors who deservedly left with all three points and a morale boosting success.
Blades: Long, Bennett (Gordon 68) Kelly, Whiteman (K. Smith 82), Wilson (Graham 60), Semple, Slater, Reed, Wright, Hallam, Brooks.
