Leeds can have a real go in the FA Cup this season and improve their awful recent record in the competition.
The Whites have managed just one quarter-final appearance in the last 28 years and their defeat to Sheffield United in 2003 cost Terry Venables his job.
Leeds were often at Wembley under Don Revie and made four FA Cup Finals between 1965 and 1973, winning for the only time in their history in 1972.
Their last semi-final appearance was way back in 1987 when they lost to eventual winners Coventry City.
With a six-point cushion, Leeds are well on course to survive in the top flight – their No 1 goal this season.
They may argue that they are not safe yet, but a run of just two defeats in 15 games suggests they will steer clear of trouble.
So boss Daniel Farke can also focus on the Cup and his substitutions at Birmingham show he is not taking the competition lightly.
He brought on skipper Ethan Ampadu at half-time to help change the tie, while Dominic Calvert-Lewin and Brenden Aaronson also made positive contributions from the bench before Leeds' shoot-out win.
Leeds have not won at Wembley since the 1992 Charity Shield, when Eric Cantona scored a hat-trick against Liverpool, and maybe this could finally be the season they change that.
