Leeds United boss Daniel Farke, speaking to the BBC: "This means a lot for us, also for our supporters we can send them back happy. In our recent history we were not too good in the FA Cup so it's good to go on a proper run, fifth round already, also such a scruffy hard fought win, sometimes these wins are the best for the spirit group. Lots of rotation today and also many players in the pitch that did not have that much minutes but we were still able to find a way in this difficult away game against a Championship side in red hot form. To find a way in a scruffy game to win it is good for my team, good for my spirit and I'm delighted.
"Birmingham were the better side in the first half, no doubt about it, but we defended everything in the end and there were some good saves by Lucas Perri. We changed the set-up, brought our captain, our leader Ethan Ampadu in and won the momentum back in the game and scored the one with a fantastic goal from Lukas Nmecha.
"We were always convinced that we could do it on penalties and that we have done. And Lucas Perri, again, very good in the penalty shootout and a good win for the team."
