Crawley were beaten 4-3 away to Peterborough in their last league game, while Birmingham are in fine form with four straight successes in the league.
They beat Bristol Rovers 2-0 in their last league game and were 2-1 winners at Barnsley in their last previous road trip in this division.
Birmingham have won three of their last four league games by at least two goals and can secure another comfortable victory.
However, with a clean sheet not guaranteed, a 3-1 win for the visitors appeals for correct-score bets as Birmingham have conceded in five of their last six league away matches.
