"It looked like there was two of him in our goal tonight - Keiren was absolutely tremendous for us," the City boss said to the media after the game.
"I can't remember one save that stood out in particular because there were so many of them. In the second half he was absolutely outstanding.

"Birmingham are a very dangerous side offensively and are very strong going forward and we did well to frustrate them at times.
"When we got the goal they got frustrated because they couldn't find a way through us and then the crowd turned on them which was what we wanted.
"We gained confidence from that and we should have scored a second one when Jay Tabb has lifted one over the crossbar.
"Overall it was a good performance from us all round because this is a notoriously difficult place to come.
"We had 11 players who were up for it tonight and I thought they were all tremendous although obviously Kieren was particularly outstanding."
