Chesterfield manager Paul Cook praised his side's defensive discipline following the 0-0 draw at Bradford.
Capital One Cup quarter-finalists City had the better opportunities but could not break through a strong visiting defence.
Their only shot on target came in the ninth minute when skipper Gary Jones saw his 20-yard free-kick turned round the post by goalkeeper Richard O'Donnell,
Cook said: "It was a very disciplined, hard-working point. Bradford are having a fantastic season, but defensively we were very strong and we restricted them to very few chances.
"It was a night when our flair players couldn't get into the game and create chances, but when you get a point away from home that is very good. It wasn't a great game, but to get a point when you are not playing particularly well is a good point."
Bradford boss Phil Parkinson also praised Chesterfield for the way they played.
He said: "It was a difficult game. I think we played some really good football, especially in the first half, but we couldn't unlock the door. A goal would have opened things up, but Chesterfield did a really good job. They played well and made it difficult for us.
"Some of our football was very good and our discipline was also good, although we got frustrated in the second half and lacked a bit of calmness. But I couldn't fault the lads.
"Credit to Chesterfield, they are a team full of confidence following their 6-1 home win over Hartlepool in the FA Cup on Saturday."
Parkinson added: "I was especially pleased with Will Atkinson, Gary Jones and Zavon Hines - we played some really good stuff. I was also pleased with central defender John Egan. It was a good debut for him after joining us from Sunderland on loan."
