Gary Rowett's men are one of a number of sides that are within touching distance of the top six.
David Davis has insisted Birmingham's players would be fools to think that they are even close to being out of the play-off race in the Championship despite their mixed form over the past few weeks, the Birmingham Mail reports.
The Blues have won just twice in their last seven games, which has seen them fall to ninth in the table. Nevertheless, Davis believes that Gary Rowett's men can take plenty of confidence into the final 11 games of the campaign.
"The top six place is still there for us, definitely. No one is running away with it and if we didn't think that we would be fools," he told the Mail.
"We are in and around the pack and we have proved we can play against the top teams - and win against the top teams.
"We are doing well against the big teams, we just need to get results against the sides that are around us. But we can only be positive."
While the Midlands side's recent form has not been the strongest, they have plenty of reasons to be optimistic heading into the business end of the season.
Their most recent victory came against automatic-promotion chasers Hull City, and that win was clearly not an anomaly as they also thrashed two play-off contenders - Derby and Ipswich - 3-0 in late January.
And with a game in hand over Sheffield Wednesday, who currently sit in that final play-off spot, Rowett's men would certainly be one of the most likely candidates if one of the teams that are currently outside the top six manage to make a late surge up the table.
