Leyton Orient boss Russell Slade hit out at his side for a "poor" performance as they crashed 3-0 at Exeter.
Jake Taylor's opener and a brace from Liam Sercombe left the O's just four points above the drop zone.
"It was a poor performance. It wasn't that we didn't create chances, it was the way that we conceded the goals that has really annoyed me and two out of the three goals were really poor," said Slade.
"Players have got to deal with defensive situations better than we did. The first goal where we have missed a couple of opportunities to get the tackle in to stop the ball going into the six-yard box."
