Sheffield Wednesday boss Brian Laws:
"It's been a great run. We knew this was going to be a game of nerves with so much at stake for both parties.
"I said each team was going to have their moments and who dealt with those better would come out on top. Unfortunately, we were not as clinical as we would have liked to have been.
"Had Kenny Lunt's shot gone in, rather than hitting the bar when it was 0-0, I believe there would have been no way back for Birmingham.
"But what we can look on is a great end to the season and I am as proud as punch with my players."
