Exeter boss Paul Tisdale admitted his side need to take a long look in the mirror following their humiliating FA Cup defeat by Curzon Ashton.
The Grecians were dumped out 3-2 by the UniBond North side, who are 97 places below them in the league pyramid.
Tisdale said: "There is no excuse for the defeat and the players will have to ask themselves what went wrong."
He added: "I didn't feel Curzon were a good side - they were average - but they had a good game plan and we contributed to our own downfall with a flurry of mistakes.
"I don't think we had any spark in the first half - they had a tactic of sitting off us and letting us play, but we didn't use the ball well enough.
"Our set-up play was excellent, but nothing really came out of it which meant we're rarely going to score."
