Both teams are going through a tough spell. Cardiff have lost almost all of their recent matches, with just one draw in their last five, and they've been conceding a lot of goals. Birmingham have had a mixed run — a couple of wins, a draw, but also some heavy defeats — so neither side comes into this looking confident.

There's no recent history between these two to go on, and both have been leaking goals lately, so the match could well be open with goals at both ends. Given how shaky Cardiff look right now, Birmingham seem the slightly more likely to come away with the win.
