Paul Tisdale could not contain his frustration at the way Exeter fell to a second successive home defeat, losing 1-0 to Burton.
Phil Edwards headed the only goal of the game from an 89thminute corner, which Exeter had needlessly conceded through captain Danny Coles.
That goal and two one-on-one chances missed by strikers John O'Flynn and Alan Gow either side of half-time led to Tisdale venting his frustration at full-time.
"They were two very good chances and you can't miss chances like that and give a soft corner away in the last minute of the game," Tisdale said.
"Their goalkeeper has made some good saves, but we should have gone round him in the first half, it was a great opportunity because he went down early and he (O'Flynn) should have gone round him and then we contrived to do it again in the second half.
"It was such a poor, soft corner to give away. But there we are, we have to learn from it. It was an absolute giveaway.
"We played well, but we gave it away. We just have to learn from it. As a team and a group, they were not heightened to the danger enough. There was an incident there between (Artur)Krysiak and Coles, they didn't make the right decision, but the whole team didn't sense danger.
"We created two wonderful one-on-ones and I am not going to complain about that because it is enough to win a game of football."
