The Iron's youth team were beaten 3-2 at Bottesford Town on Saturday lunchtime.United's youngsters raced in to a two-goal lead within the opening 20 minutes of their final pre season game.
The Iron opened the scoring after 15 minutes following some excellent passing play but were fortuitous to get the lead when the Bottesford keeper sliced his clearance into his own goal.
United's system was causing the home team real problems and it was the Iron's youngsters who scored again on 20 minutes.
Noel Burdett was through and on the verge of the penalty area when his legs were taken from under him.
Connor Purdue stepped up and whipped his free kick around the wall and into the far corner with quality to put Tony Daws' team in to a fully deserved and commanding lead.
United dominated the first half as they moved the ball around the pitch with confidence and produced some neat passages of attacking football that Town were finding difficult to stop.
This all changed within the space of three minutes as Bottesford somehow went in at half-time level.
United goalkeeper Ben Ledger was beaten from outside his penalty area on 43 minutes from what seemed like a routine save but the ball crept in low down to his left hand post as the home team pulled a goal back.
On the stroke of half-time the referee awarded a very disputable free kick against the Iron on the edge of the box.
The resulting free-kick appeared to catch the visitors shotstopper too far off his line and as Ledger back peddled the ball hit the bar and struck the Iron's first year keeper on the back before crossing the line.
United trudged off the pitch at half-time wondering how they had been pegged back when they had ran the game.
The second half saw the home team on top well marshalled by former Iron Lee Ridley and supported by his team mates including Tom Johnson, Jack Cross and Danny Gibbons, all players to have graduated from United's academy.
The Iron's youngsters seemed a different team and were not helping themselves - giving possession away too often and consequently couldn't build on their first half superiority.
Bottesford nudged themselves into the lead on 75 minutes.
United centre back Charlie Clemenshaw tracked the home team striker to the corner flag and made a needless rash challenge giving away a free kick.
As the ball was whipped in to the near post there seemed little danger but Levi Sutton stretching to clear the ball unfortunately turned it into his own goal and United were behind.
Both teams had further chances as the game drew to a close.
Afterwards, Academy Manager Tony Daws said: "In the first half Paul Harsley and I both thought that our play was outstanding from a tactical and technical perspective, there were so many positives to take from individual and the team performance.
"In the second half we looked a different team. It was clear that conceding the two late goals at the end of the first half had affected our players.
"From a development perspective this is all part of their psychological learning, how to deal with making mistakes and how to recover from conceding goals.
"As usual we will debrief the game on Monday and all players will be given feedback as to areas of their game that they did well and areas that they need to improve on.
"It has been a good pre-season, we are injury free, our players look very fit and we are looking forward to the commencement of the Football League Youth Development games programme next weekend."
