Goal-scorer Lee Angol was frustrated by the Bantams' Emirates FA Cup exit, after a third-and-final first-round clash with Exeter City.
The Bantams conceded two second-half goals at St James Park to seal their FA Cup fate in Devon.
Angol stressed his disappointment at the result, as well as City’s second-half performance and failure to capitalise on the early goal.
He said: “It is frustrating. We do it to ourselves as a team. We are good enough to beat anyone and just shoot ourselves in the foot.
“We say the same thing every week. We are not clinical enough and that came back to bite us again.
“We did not finish the game the way we started it. The feeling is probably worse because of how we played in the first half.
“We have got to start killing teams off, because that is what we have been missing, in the last few weeks especially.”
Angol was quick to look for the positives from the disappointing result, insisting his side can now fully focus on picking up points in the league.
City’s No.19 knows the result leaves the Bantams with no choice other than to concentrate on their league form, suggesting the lack of cup competitions could prove beneficial in their pursuit of promotion.
He added: “We have no real choice but to focus on the league, now.
“At the end of the day, all we want to do is get promotion. Maybe it will turn out to be a blessing in disguise, as we can only have one aim now.
“We just have to keep moving on and keep working hard. Hopefully, in the next game, we will get the win and build from there.
“I do feel like, once we get the wins, the belief in the squad will grow and we will keep winning.”
