Bantams boss Mark Trueman admitted his disappointment and frustration - following his side’s 2-0 defeat to Crawley Town.
City fell to their first home defeat in 11 at the hands of the Sussex-based side, thanks to goals in each half from Jordan Tunnicliffe and Joe McNerny.
Trueman bemoaned his side’s start to the game and inability to take chances against the Red Devils.
He said: “It was a difficult game. I thought we did not start as well as we should have done in the first half.
“To concede early on - in the way we did - was always going to open the game up, and that is what happened in the second half.
“We threw bodies forward and made plenty of changes but just, for whatever reason, could not find a goal, then were hit with a set play.
“We had 20 attempts but not scored any goals, so have to have a look further at that - and see why it is that we were not good enough - and improve.
“We pushed for goals in the second half, and made changes in order to try and put ourselves in the best-possible position, but it was not our night.
After the Bantams’ five-match unbeaten run was brought to an end, Trueman is determined to see his side respond from the setback ahead of Saturday’s trip to Harrogate Town.
With six games of the Sky Bet League Two season remaining, the City chief insists his players will ensure they keep pushing to finish in the highest-possible position.
He added: “We have got to stick together when we lose games. We have not really been used to losing too many, and so our reaction is very important.
“We have a trip to Harrogate on Saturday, and it is about how we respond. We have to be positive and ‘at it’ - so we can learn and move on.
“That is probably the first time at home we have looked more vulnerable in our own box than our opponents.
“We are frustrated, but have to show our character and keep on fighting until the end.”
