While the Canaries are well placed to earn promotion to the Premier League, Blues needed a 1-0 win at Sheffield Wednesday at the weekend to move out of the relegation zone.
On the back of defeat at promotion rivals Swansea City, Daniel Farke and his players came under fire after a number of concerning performances.
However, the Canaries have responded with three successive victories, their latest success over Rotherham United extending their lead to seven points over the chasing pack.
Norwich were further boosted by the defeats suffered by Brentford and Swansea City, and there is a window of opportunity for the club to cement their status at the top with 15 matches remaining.
The East Anglian outfit were again indebted to Teemu Pukki at the weekend as the Finn took his return to four goals from three appearances with the decisive strike against the Millers.
With just three goals being conceded in six fixtures at the other end, Farke will be optimistic about his team's chances of extending their lead over the coming weeks.
As far as Birmingham are concerned, head coach Aitor Karanka is said to be fighting for his job at St Andrew's as Blues flirt with relegation to League One.
Although a 1-0 victory was recorded at rivals Sheffield Wednesday on Saturday, the Spaniard is aware that one positive result every few games will not be enough to keep him in the dugout.
Despite their current situation at the bottom of the table, Birmingham now possess the eighth best away record in the division, collecting 22 points from 16 games.
Nevertheless, nine points from 15 games at their West Midlands home is the difference maker, heaping the pressure on Karanka and his squad to end a winless run which stretches back to October 28.
Birmingham City Championship form: DDLLLW
Norwich City Championship form: DDLWWW
Despite witnessing his side only prevail 1-0 against a 10-man Owls side, Karanka may select the same Blues XI for this contest.
Barring any late fitness issues, Farke also has little reason to make any alterations to his Norwich side.
Birmingham City possible starting lineup:
Etheridge; Colin, Dean, Clarke-Salter, Pedersen; Gardner, Sunjic; Sanchez, Harper, Bela; Hogan
Norwich City possible starting lineup:
Krul; Aarons, Hanley, Gibson, Giannoulis; Rupp, Skipp; Buendia, Vrancic, Cantwell; Pukki
We say: Birmingham City 0-2 Norwich City
Having got an important three points on the board at the weekend, Karanka will feel that some pressure has been lifted ahead of this game. However, despite the opportunity to play with more freedom, we still expect the visitors to record a comfortable win at St Andrew's.
