Birmingham have scored no more than one goal in four of their last five matches, while maintaining a relatively solid defense. West Bromwich Albion are in a deep crisis, scoring just one goal in their last five matches and conceding 11, indicating serious problems in both attack and defense.
Their head-to-head record also points to a recent trend of low-scoring games. The teams drew 1-1 in their first meeting of the season. Earlier matches, despite some high-scoring performances, are less relevant in the current context, given West Bromwich Albion's sharp decline in form.
Given the visitors' weak attacking play, their psychological state following a series of defeats, and Birmingham's cautious style, which is not prone to high totals in games against evenly matched teams, it's logical to expect a low goal total. Most likely, the teams will score no more than two goals between them.
