Birmingham have had a mixed run lately - a couple of heavy losses, but also some wins and a draw. That shows they're not in great form but can still pick up results. Watford have also been up and down, with some tough losses and a couple of wins, so neither team is really flying at the moment.

These two haven't met recently, so there's no history of high-scoring games between them to go on. Both teams have looked shaky at the back, though Watford have struggled to score, so this looks like a fairly close game. Birmingham are at home and slightly stronger going forward, so they look the more likely side to edge it, but a draw is also very possible.
