Jonathan Spector is certain Blues are 'on the right track'.
After such an inconsistent and frustrating start to the season, Blues are beginning to function a lot better.
The American international says Blues must maintain recent improvements over weeks and months and not slip back into bad habits.
Blues tackle Steve Bruce's Hull City at St Andrew's on Saturday, buoyed by a victory over Bristol City and a hard-fought and deserved draw at Blackburn Rovers.
"I think we all knew wed turn the corner and start getting the results we want, that we need, to move up the table and ultimately attain promotion," said Spector.
"It's taken a little longer than we hoped but we have always been confident in our ability to do so and I think were there now.
"Obviously with the draw and the result from last Tuesday, thats two decent results and they were important for us.
"We always knew the results would come and I think we are on the right track.
"We have to make sure we are consistent.
"Our home form hasn't been great, which is the opposite to last season.
"It was good to get that home win (against Bristol City), and the performance as well. Hopefully we can kick on from it.
"It's a difficult league, very competitive, very tight. A few wins and decent results like Saturdays away from home we will certainly be moving up the table."
Spector praised the contribution of Blues striker Marlon King.
"He is very much in form at the moment, which is great," said Spector.
"It's always important to have your strikers scoring goals, and Marlon is doing that.
"And if we can get some others in on the action as well it would be fantastic."
