Dino Maamria was sacked as Burton manager following his side’s 2-1 defeat to promotion-chasing Stevenage.
Deji Oshilaja gave Albion a seventh-minute lead, converting the rebound after Joe Powell’s penalty was saved by Taye Ashby-Hammond.
But Kane Hemmings struck against his former side on the stroke of half-time and Jamie Reid kept his cool from the penalty spot to condemn Burton to a fifth defeat in six winless games in League One.
That run has seen Burton slip down the table, with Maamria leaving them in 19th place, four points above the relegation zone.
A statement from chairman Ben Robinson read: “Dino Maamria has been relieved of his first-team duties with immediate effect.”
Maamria performed his post-match media duties but was in sombre and reflective mood of not only the game but his time at the club before learning of his departure.
“I thought we started well in very tough conditions,” Maamria said.
“We dealt with a number of long balls and then went ahead, deservedly, I thought and then last minute of the half we switch off at the back post and then they score to go in at half time one-one.
“Second goal it comes from a poor throw out and their players pick it up. KB (Kwadwo Baah) is trying to get back in position but they get a penalty.
“It is tough to take. Ultimately I have been at this club two weeks short of three years and I have loved my time here. I think the fans have been magnificent with me throughout that time, a lot of players and a lot of staff.
“It is a winning business and I haven’t won enough games. We had a good October but overall I understand the fans frustrations. Football is a winning business and we didn’t win today.”
Stevenage boss Steve Evans hailed his side as they maintained their League One promotion push.
Evans, whose team are third, said: “It was an outstanding performance. Maybe we were still trying to deal with the conditions in the first 10 minutes and we were a bit sloppy leading to them getting the penalty.
“We had a perfectly good goal disallowed with one that was over the line, having seen the footage and the stills, but in fairness to the referee there were a lot of bodies in the way but then you look to the assistant, so we felt a bit hard done to.
“I thought we became really strong in the last 20 minutes before half-time, got the goal, and perhaps we should be turning round in front, despite the penalty and then, I think, second half, we controlled it. It was inventive and it was bright.
“For 70 minutes, how could you not be commending that sort of performance and we come away with a very hard fought and deserved three points.”
