Callum Cooke was "brutally honest" in his assessment of yesterday's defeat to Crawley Town.
In the wake of the Bantams’ 1-2 loss to Crawley Town, City’s No.8 insisted he and his colleagues must have difficult discussions about the performance which led to the result.
Two second-half goals for the visitors saw them snatch all three points from the Utilita Energy Stadium and Cooke gave a scathing review of the second 45 minutes.
He said: “The second half performance, being brutally honest, was not good enough.
“It was not good enough at any level, let alone in League Two.
“You get what you give in football, and unfortunately we have not defended our box as well as we should have.
“Something has to change. There have been some very harsh words in there which were needed.”
Cooke also questioned City’s desire to win, signalling to their failure to kill the game off after a dominant first-half performance.
The 24-year-old suggested his side must perform to a consistent level throughout the entirety of a match.
He added: “We all know football is a game of 90 minutes, a game of two halves.
“You cannot just play well for 45 minutes and expect to win a game of football. It just does not happen. We lack that killer instinct.
“We have another game in 72 hours which we will hopefully be able to put this result behind us in, but as for this game it was just not good enough across the whole game.”
