Birmingham City, unbeaten in 11 home games, face Leeds United who have won four of their five previous FA Cup meetings. The Blues have lost just one of their 11 games since Christmas while Leeds have suffered only two defeats in their past 14 matches.
Leeds knocked out Derby County 3-1 in the previous round and are seeking to avoid consecutive fourth-round exits, having been eliminated at this stage last season by Millwall. Birmingham is targeting their first FA Cup fifth-round appearance since 2019-20.
