Meanwhile, the Blues head into the contest in the West Midlands having recorded three successive wins - a run which has moved Pep Clotet's side clear of a relegation battle.
Having talked up his side's chances of getting the better of out-of-form Leeds United on Tuesday night, Thomas Frank would have been frustrated that his Brentford side could only claim a share of the spoils.
However, when looking at the bigger picture, the Bees boss will be content with having prevented the second-placed side from extending their advantage at a time when the clubs around them are struggling for consistency.
Despite only recording eight points from their last five matches, Brentford sit in fourth spot, two points adrift of Leeds and five clear of eighth position.
Aware that more winnable fixtures - on paper - are to come, Frank will feel that his team are in an excellent position ahead of the next period of games, although there will be an acknowledgement that they cannot overly rely on their free-scoring front three.
Just two clean sheets have been kept in their last 10 outings in the league - something which must improve if Brentford are to maximise their potential over the coming months.
At the turn of the year, Birmingham would have been regarded as weak opponents after just one triumph in a dozen second-tier fixtures from the start of November to New Year's Day.
That is no longer the case, however, with Clotet witnessing his team put together a nine-match unbeaten streak in all competitions, which includes 14 points being registered from their most recent six Championship games.
While wins over Nottingham Forest and Bristol City stand out, Clotet and his players deserve huge credit for the run of form as a whole, with Blues also reaching the FA Cup fifth round.
Ten points adrift of the top six, the playoffs may just be out of reach, although Clotet will stress to his team that two or three more victories in succession will heap the pressure on the teams above them.

Having witnessed his team grind out a win at Barnsley, Clotet could keep changes down to a minimum.
Like their hosts, Brentford are unlikely to make many alterations to their starting lineup for the game at St Andrew's.
Birmingham City possible starting lineup:
Camp; Colin, Clarke-Salter, Roberts, Pedersen; Bellingham, Gardner, Sunjic, Bela; Hogan, Jutkiewicz
Brentford possible starting lineup:
Martin; Dalsgaard, Pinnock, Jeanvier, Henry; Jensen, Norgaard, Dasilva; Mbeumo, Watkins, Benrahma
We say: Birmingham City 1-2 Brentford
While Birmingham are the form team heading into this game, we cannot back against Brentford, who have shown numerous times this season that they respond well to disappointing results. However, the Bees will have to play to their best to out-work their hosts.
