After watching his youth team come from two goals down to claim the scalp of Premier League side Aston Villa in the FA Youth Cup, Mark Smith was unsurprisingly elated.
The second Villa effort came 60 seconds after the half time break, but stunning goals from Jordan Walshaw, Kabine Dumbuya and Tope Fowodu turned the tie on its head and in the Spireites' favour and they claimed an incredible 3-2 victory.
Despite the deficit, Smith felt his side always had the ability to come back and get something from the third round tie.
He said: "I don't know about the stats and stuff like that, but we've got a good set of kids with great spirit and there have been a number of times we've gone behind this season in our league games - but we've always seemed to come back.
"There's a never-say-die attitude and I thought that once the first goal had gone in there was only going to be one winner if I'm honest."
Behind by a goal at the break, Smith said he was pleased with the first half performance, but wanted to keep things tight to start the second.
Smith said: "We were quite happy with the first half, we thought we started really well in the first ten minutes, but then they showed that they're a decent team with some decent players and they shaded the rest of the half.
"We went in a goal down and we thought we were still right in the tie, but we needed not to concede in the first ten minutes of the second half - then we conceded in the first minute.
"But again, in our side and on the bench there was no doom and gloom. As soon as we got the first one - and it was important that we got it so early - we gradually got on top."
Smith compared the game to some of his highlights as a player, rating it just as highly.
He said: "As a player I've been fortunate. At Barnsley we had a run to semi finals and lost over two legs and I've beaten Manchester United at Old Trafford.
"But to beat a Premier League scalp like Aston Villa with our team is on a par with any of that - and I'm sure we'll realise that as it sinks in a little bit."
