Sheffield Wednesday travel to St Andrews on Saturday looking to pick up only their second away win of the season.
On paper this looks an unlikely occurrence with Birmingham sitting on top of the Championship table and Wednesday shipping a hatful of goals on their travels.
Wednesday have a number of injury doubts ahead of the fixture. Brian Laws made five changes to the side that beat Sheffield United last weekend and this resulted in a poor display at Barnsley on Tuesday. Further changes are inevitable but just how many remains to be seen.
Jermaine Johnson should return following his 1-match ban but Tony McMahon will miss out as begins a 3-match suspension.
Steve Watson could return to the starting lie-up as could James O'Connor while Captain Richard Wood faces a late fitness test.
In attack there are doubts over both Deon Burton and Marcus Tudgay but Akpo Sodje could return to the squad after sitting out in midweek as he steps up his return to match fitness.
The Owls go to Birmingham with one of the worst defensive away records in the league, having not kept a clean sheet on the road this season.
Birmingham have a wealth of talent at their disposal to capitalise on the Owls defensive frailties.
Quincy Owusu-Obeyie missed the midweek win over Crystal Palace but could be back in contention as could Scotland international James McFadden.
Other attacking options for the Blues include Kevin Phillips, Cameron Jerome, Marcus Bent and Garry O'Connor with Swedish international Seb Larsson providing the service.
Wednesday have won one and lost the other three of their last four visits to St. Andrews. Birmingham have won 5 and lost 1 at home in the Championship this season and have conceded just 1 goal in those 6 matches.
