Derek Adams was again left believing his side should have been further ahead in the game, following City’s 2-1 defeat in the Emirates FA Cup first-round 'replay replay' at Exeter City.
The Bantams were in front at half-time, but two second-half Exeter goals meant City were defeated.
Adams believes his side should have extended their lead before the break, and slammed his side's "shocking" defending.
He said: "With the amount of good opportunities we had in the first half, we should have been further ahead in the game.
"Exeter did not have many, if any, opportunities in the first half. The chances they did have were through our mistakes.
"The two goals to lose the game were really shocking."
Adams is aware the same mistakes have reoccurred all season, and is left looking at similar issues to the ones which have cost his side when they have been unable to secure three points.
He insists City must be more clinical in both attack and defence.
The Bantams boss added: "Throughout the season, we have not been clinical enough or scored enough goals to put the opposition to bed.
"Once again, it was a similar story tonight.
"We cannot keep making really good opportunities and not finish off teams.
"What has happened to us is that we have not kept enough clean sheets. That has not helped us either."
