Steve Watson was hoping for shades of the 1966 World Cup final when Nathan Ellington's strike cannoned off the under-side of the crossbar.
Ellington's last-minute shot beat goalkeeper Maik Taylor but West Bromwich Albion were denied the victory they deserved as the woodwork came to Birmingham's rescue.
Watson was praying for a 'Geoff Hurst' decision from the linesman but was disappointed.
"I thought we were clearly the better side," said Watson. "We looked like we had won it at the end with Nathan's shot. I was hoping it would be a 1966 situation where the linesman flagged to say it had crossed the line."
"I think it's been a long time home or away that we have had so many chances. We were desperately unlucky. I'm not sure our keeper had a direct shot to save all game.
"Overall we've got to take a lot of pluses out of that. We would have loved to have opened up a psychological gap on them but it was vital we didn't lose."
Ellington's goal was his first since a consolation effort in November's Carling Cup defeat at Manchester United. Yet self-belief was never an issue, according to the striker.
He said: "I've been confident, even though I haven't scored for a while, that I can come on and make a difference and that if I get a chance I'm going to score.
"It was good to get off the mark again and important we didn't lose against Birmingham. That could be the point that proves the difference come the end of the season.
"We are confident we're going to stay up and we have been all along. It's just great we haven't let them take control of the situation; it's still in our own hands."
