Sheffield United's Under 18s made it six wins on the bounce to move ahead of opponents into second in the league with a dominant victory at the Oakwell training ground on Saturday morning.
In wretched conditions which made the second half in particular a scrappy affair, the young Blades flew out of the traps to lead 3-0 at the break, and it could have been more.
It took just three minutes for United to make the breakthrough thanks to Ryan Viggars' header from a corner, the Blades number nine a handful throughout and almost opened the scoring even earlier when his low effort was saved after all of 30 seconds.
The Barnsley defence struggled to handle Viggars and the striker had chances to double his tally before Leo Gaxha got his first of the afternoon on the half hour mark.
A neat move which saw Daniel Jebbison slot the ball through via a Zak Brunt dummy which opened up the space for Gaxha to take a touch and hammer the ball into the corner to make it 2-0.
Brunt fired wide immediately after with Gaxha once again well placed to his left but the forward did get his second of the afternoon before the break when a poor pass out from the back was intercepted and he rolled the ball home from the edge of the box.
Viggars somehow slid a low ball from Brunt wide from just yards out as the Blades ran riot in the first half, but the second was a much quieter and scrappier affair as the pitch struggled to cope with the constant torrential rain throughout.
It was the hosts who came closest ten minutes into the half, somehow being denied three times in a matter of seconds as first a block, then the post denied them before a third effort got stuck on the line as both six-yard boxes were overcome by mud as the rain continued.
United's centre-back duo of Finley Potter and Harrison Foulstone put bodies on the line to block out anything the hosts threw at them and the Blades nearly found a fourth in stoppage time when Hassan Ayari saw his effort stop on the line when it looked like he'd beaten the goalkeeper.
The victory leaves the Under 18s trailing leaders Wigan Athletic by five points but United hold three games in hand ahead of the meeting between the two sides at the Steelphalt Academy next weekend.
