Chesterfield manager John Sheridan acknowledged his side were rather fortunate to pick up a 2-1 win over Southend.
Scott Boden's last-gasp strike gave the Spireites the win though it was a sucker-punch for Southend, who had dominated large periods of the second half.
Sheridan said: "We were fortunate to win the game but I'll take the three points. The pleasing thing is that we went right to the end.
He added: "Southend have good players in their side who are experienced and have been around. I knew it would be a very tough game.
"We're quite exciting to watch and we attack when we're at home so teams will try to make it difficult for us. I thought Southend frustrated us at times and we never really got going. That's full credit to them.
"At 1-0 up we were doing silly things. We've got to learn how to control the game. We allowed Southend back into it but we kept going and we didn't hide. The right thing to do was to go on and win the game rather than settling for a point.
"We're showing a bit of character. I think we've got a bit of depth in the squad and we've got a good dressing room. We've got to stick together but we've got lots and lots of work to do."
Southend United boss Paul Sturrock was inconsolable following the loss.
He said: "I'm absolutely gutted. Football kicks you in the teeth at times. For 85 minutes we were fantastic but we lost our way in those last five or six minutes.
"With hindsight the substitutions were perhaps made at the wrong time. It disrupted the team. However if I was able to surmise what's going to happen then football management would be easy."
