Alex Inglethorpe admitted that conversely he was pleased his Under-18s surrendered a 3-0 lead before beating Leicester City at the weekend.
The lads looked to be coasting to a fourth-successive win and sixth-successive clean sheet in the FA Premier Academy League as a double from Jon Obika and Yaser Kasim's strike handed them a 3-0 lead against the Foxes just past the hour mark.
However, the home side hit back with three goals in the space of 10 minutes to rock the lads and make it 3-3.
Thankfully Adam Smith produced a last-minute cracker from 30 yards to take back maximum points.
"In the bigger scheme of things conceding those three goals will be a good thing for us," explained coach Alex.
"For 65 minutes, we were outstanding against a really strong Leicester side. They had three Under-19 players in the spine of their team but for that first 65 minutes it was as well as we've played. The wake-up call came at 3-0 up and underlined what can happen if you switch off or lose concentration.
"Once it went back to 3-3 we were able to secure the winner that we deserved.
"If the referee had blown up after 65 minutes, there were some faultless performances but in a funny way I'm glad with how things happened because it will give our defenders a lesson they can take forward.
"We'd kept five clean sheets and you could start believing you are better than what you are, the lads were sailing towards their sixth clean sheet but had a nasty bump. There are a few points that will be useful for the future."
