Caretaker manager Gary Rowett was frustrated by the ease with which Aldershot saw off his Burton side 4-0.
Goals from Peter Vincenti and Wilko Risser and two from Guy Madjo condemned Burton to a miserable home defeat just seven days after their 7-1 mauling at Bristol Rovers.
"I put a team out that gave the lads an opportunity to make up for a poor performance but it was disappointing again, especially the energy levels," said Rowett.
"I'm not being disrespectful to Aldershot, but all they did was kept their shape, got the ball forward and had people running into good areas. That was enough to hurt us and they didn't need to play fantastic football to beat us.
"It's been a few times now this season where we've conceded a second goal and our reaction has not been what you would want it to be.
"If you look at where the goals came from, nearly all of them were the result of our mistakes. You don't stay in games if you hand goals to the opposition on a plate."
