Paudie O’Connor insisted he feels supporters' frustrations, after City's "unacceptable" performance in their defeat to Hartlepool United.
The Bantams lost 3-1 at the Utilita Energy Stadium, their first league defeat at home this season.
Despite pulling a goal back for City in the 72nd minute, O'Connor was disappointed by his side's showing.
He said: “No one is as frustrated as we are. We echo the supporters' disappointment.
“None of us thought that performance was acceptable.
“After a decent performance for most of the game on Saturday, how we did was disappointing.
“We cannot afford many more of those performances this season.
“All we can do is try and give better on Saturday, to make the fans proud.”
City’s No.4 felt the early goal for Hartlepool made the game difficult for Derek Adams' men to compete properly in, though admitted the Bantams were second best throughout.
The Irish defender added: “When you go 1-0 down against a team with a lot of bodies behind the ball, you really do not help yourself.
“Any time we have got a decent result this season, we have gone 1-0 up against a team - especially at home.
“We have to give Hartlepool credit for the way they set up.
“They made it very hard for us. They had a lot of bodies behind the ball and defended their 18-yard box very well.
“We will try and put it right on the training pitch come Thursday, then go to Swindon and hope to get a result.”
