Gaffer's View: Time To Walk The Walk
The win which came about after a couple of goals for Marlon King and a long range strike from Wade Elliott twice brought City from behind to win the game 3-2.
It was only a second home win in seven attempts for Birmingham as they ended a four-match winless run.
And Clark wants more of it.
He told reporters: 'Now we have to kick on. We cannot have any of the nonsense we've had all season where we get a couple of positive results like Blackpool (a 1-1 draw at Bloomfield Road in midweek) and today, and then come unstuck next weekend at Wolves. We've got to kick on now.'
He continued: 'Talk is cheap. Too many people talk the talk - you've got to walk the walk.
'Any team who wants to be successful has to go on a run of games where there's more wins, although you can sprinkle in a couple of draws, but you've certainly got to have an unbeaten run with a lot of wins in there to kick you up the table.'
