Dean Holdsworth was delighted to see Aldershot secure the double over promotion-pushing Southend this season.
Danny Hylton's header from close range just before the hour handed Shots all three points and came after they defeated Blues 2-0 last month after the original fixture had been abandoned due to floodlight failure with Southend leading 1-0.
"The team have shown in the last two performances that you have to have the right ingredients to win football matches," said Holdworth. "Southend have been fantastic over the season for Paul Sturrock and we knew it was going to be a very tough game.
"I freshened up the team from the Bradford game and the lads have worked their socks off and I'm delighted for them. The decisions we have made to change the team have made a difference and that is pleasing too.
"It's really important that you do your homework on teams and believe you can score. You need a threat in the game and we had that and were comfortable in defence. I think the lads have put their bodies on the line and Jamie [Young] has not had a save to make as we restricted Southend to shots from distance.
"We don't have a game this weekend but we will be ready to face Bristol Rovers next Tuesday."
Holdsworth admitted he did not know the match marked the 20th anniversary of Aldershot FC's final match before being wound up in the High Court. But he said of Aldershot Town, which grew out of the ashes of the old club: "It was fitting that we won."
The defeat, coupled with Shrewsbury's 1-0 win over Cheltenham, saw Southend drop back out of the automatic promotion places as their stuttering home form continued to disrupt their push to go up. Blues have won 12 times on the road this season but have only won eight times at Roots Hall, drawing six and losing five other matches.
Sturrock, whose side fall from third to fourth place, said: "For the first 45 minutes we played some decent football and in the second half they scored from their only chance, but credit to them. We let ourselves down and our goalkeeper did not have a save to make.
"We are still trying to find a formula at home that works but it's not easy and we keep shooting ourselves in the foot. With this defeat we are under added pressure now because we have some tough games coming up against teams around us in the table. It's difficult to bring players in but we need to bring in two or three before the loan window shuts."
