A young and understrength Chesterfield youth team lost 4-3 to Rotherham United on Saturday, despite leading 3-0 at half time.
George Lynam put the Spireites on their way before Derek Daly struck twice to give Chesterfield a lead that looked strong.
However, a fine Millers fightback after the break saw the game turn on its head and two late goals handed the hosts an unlikely 4-3 win.
Assistant Professional Development Phase Coach John Bilton gave his feedback on the match.
He said: "There were some very pleasing things that came out the game because we started predominantly with first years and even one under 16, as well as some young lads who came on as substitutes.
"Considering the age of the side, we started very well. I told them to aim for two goals before half time, but we actually got three. Normally with a three goal lead you win the game, but unfortunately we weren't good enough defensively in the second half.
"Our defence is still a work in progress, we conceded an own goal which was unlucky, but the ball shouldn't have been able to get in the six yard box in the first place.
"We then conceded a penalty when we shouldn't have and the third was a real sickener as it ricocheted to a man who was two yards offside after we'd pushed up.
"That third goal was on 87 minutes and the final goal was on 93 minutes and was their only really decent goal.
"It's a game we really should have won, but there were a lot of good performances from the players, especially going forwards."
