Before the Blues' win over Cardiff last Friday, Gary Rowett's men had gone five games without a win.
Before last Friday's narrow victory over Cardiff City, Gary Rowett's side had gone five games without a win in the Championship, and had slipped outside of the top six. Despite the poor run, there were some positive signs that would have given Rowett hope.
A stalemate with free-scoring high-flyers Middlesbrough was followed by an away draw against Preston North End. Simon Grayson's men boast one of the strongest defences in the division - despite their lowly position in the table - yet, the Blues had several golden opportunities to get back to winning ways at Deepdale.
But they finally managed to end their run, against the Bluebirds, and Davis believes that their last three performances show plenty of the qualities required of a top six side.
"Is the play-off charge back on? Yes, why not?" Davis said to the Mail.
"We have played some very good teams over the past three games, especially Middlesbrough away - that was a good performance from the boys because they had done very well.
"For us now it's just about climbing that table."
Having seen off one of their play-off rivals last week, the Blues face another on Boxing Day as they travel to Hillsborough to face Carlos Carvalhal's Sheffield Wednesday. The Owls - who sit 7th in the table, one place above Rowett's side - ended their own poor run of form in their most recent game, as they demolished Wolves 4-1 to bag their first win in five.
And while Davis' belief is that Birmingham are currently well poised for a play-off push, his hopes may be somewhat dashed should Wednesday come out on top on Saturday. But a victory against the Owls would confirm that the Blues are undoubtedly contenders for a place in the top six.
