The way Gillingham lost Saturday’s game at Burton was “totally unacceptable” to boss Justin Edinburgh.
Burton headed home a corner in stoppage-time to claim a 2-1 win.
Edinburgh said: “I am bitterly disappointed that we have lost another football match.
“It was a basic error. Three minutes (of injury-time) to go, with what’s at stake, someone has a free header in the box. You just can’t accept that.
“We should have been leaving saying we got a draw against a side who look like they are going into the Championship, but we haven’t.
“What is hurting me is the way and the manner of the goal, the free header in the six yard box is totally unacceptable.”
Edinburgh felt his side deserved something from the match, having fought back from a goal down to level through Cody McDonald.
He said: “I thought we started slowly and were hanging on but we weathered the storm and, if I am honest, the first goal was against the run of play.
“Credit to the players, they regrouped and we spoke about one or two things that perhaps weren’t going right for us in the first half.
“We were worthy of the equaliser and we had one or two other efforts that may have got us the lead. From our performance we deserved something out of it.”
Despite the defeat the Gills are still in with an outside chance of making the play-offs.
The Gills boss said: “What happens after is something we will look at on Monday but I am more angered at the way we have conceded a goal in stoppage-time from a set-piece off a free header.”
