Pick of the stats: Birmingham City v Leeds United

Birmingham City will look to extend their eight-game unbeaten run in all competitions when they welcome Premier League side Leeds United to St Andrew's in the FA Cup fourth round on Sunday (kick-off 12:00 GMT).

Blues have lost just one of their 11 games since Christmas (W5 D6) and are unbeaten in 11 matches on home soil since a 3-2 defeat to Hull City in the Championship on 18 October (W6 D5).

The Whites are also in relatively strong form, with just two defeats in their past 14 games (W5 D7) and they knocked out a second tier side in Derby County with a 3-1 away win in the third round.

• Birmingham City have won three of their past four home matches against Leeds, all in the Championship and all without conceding. The other match in this run saw Leeds win 5-4 in December 2019 under Marcelo Bielsa.
• Leeds United have progressed from four of their five FA Cup ties against Birmingham, knocking them out in 1971-72, 1976-77, 1997-98 and 2012-13 – the other was a 3-0 win for the Blues in the third round in 2004-05.
• Birmingham are looking to reach the FA Cup fifth round for the first time since the 2019-20 campaign – they have been eliminated in six of their previous seven ties at this stage.
• Leeds have now reached the FA Cup fourth round in the past four seasons – as many times as they'd managed in their previous 19 seasons combined. The Whites were knocked at this stage by Millwall last season but haven't gone out in the fourth round in consecutive seasons since 1992-93 (vs Arsenal) and 1993-94 (vs Oxford).
• Since January 2000, Leeds have been drawn away from home in 37 of their 47 FA Cup ties, including 16 of their ast 19 (including this tie). Among teams to play more than 10 ties since 2000, Leeds have comfortably been drawn away in the highest percentage (79%).
