Frustrated Colin Todd reckons City's players only have themselves to blame for yet another miserable loss.
The struggling Bantams fell to their fifth defeat in six games - and their fourth consecutive loss at home - with a painful 3-2 home reverse against Brighton.
The performance was much improved on the Blackpool debacle seven days earlier, City showing great determination to draw level having fallen 2-0 behind.
But their battling efforts were ultimately in vain as they conceded a gut-wrenching last-minute winner at Valley Parade.
Frustrated boss Todd was unimpressed though as he saw City slip a place to 15th.
"Funnily enough, when we equalised Nathan Doyle came over to the touchline and I said to him make sure we don't go gung-ho'," said Todd.
"I said keep two solid banks of four, but what happens? We lose the ball on their 18-yard line, Brighton play two passes and they are in in the last minute. It's just bad play. We need that resolve and resilience to make sure we do the job.
"I don't think we deserved to lose but what happened wasn't acceptable."
Dean Windass struck his 200th career goal - some claim it's 205 - with a 55th-minute penalty to begin City's fightback and when Steven Schumacher smashed a cracker ten minutes from time, the hosts had all the momentum.
But Brighton clinically exposed them with a classic counter punch courtesy of substitute Dean Bowditch right at the death.
Shocked City were left on their knees again and Todd admitted: "It kills you losing a game like that.
"We're getting punished for little mistakes but also we're not playing with the fluency we had at the start of the season."
Todd has injury problems ahead of the FA Cup tie with Crewe at Valley Parade on Saturday.
City lost Marc Bridge-Wilkinson before kick-off when the midfielder failed a late fitness test and left back Richard Edghill limped off in the first half with a hip injury.
