Birmingham concede only 0.83 goals per away game with one of the league's best defences, have won all four previous meetings and hold roughly three times Lincoln's squad value, giving them a clear edge in both quality and psychology. Lincoln are 1W2D3L at home, ship 2.17 per game and have already collected three red cards; their 4-1 win over Burnley flatters a leaky back line. Birmingham's narrow 0-1 loss at Cardiff also points to a tight, low-scoring contest, so the draw must be kept firmly in play.
