The visitors produced yet another Jekyll and Hyde performance to twice draw level only to see Derby County win the match 3-2.
It was an inconsistent display from Blues who at times looked at their worst but equally managed to produce some of their best spells of football.
All in all, Clark felt the game was a microcosm of Blues’ npower Championship season so far.
“The first-half wasn’t a true reflection of us and in the second-half I thought we played very well,” Clark reflected to bcfc.com. “That sums us up this season, we’re a different team in the same game.
“We’re so up and down. I was really pleased with what we did in the second-half and that deserved something from the game.
“It’s frustrating tonight because it’s happened in the same game. We weren’t at it at all in the first-half and then second-half we’ve come out and been really positive.
“We’ve conceded the third goal by us having lots of bodies in their box trying to get the winner ourselves. I’ll never criticise the players for that.
“If we play like that in the second-half from the first whistle then I’d be confident enough to say that we would have got a positive result here today.”
On a frustrating evening in front of the live Sky Sports cameras, one huge positive for Blues was a 30 minute cameo from new-boy Rob Hall.
The 19-year-old, who signed on loan until January from West Ham United on Thursday, made an immediate impact and won the penalty that Marlon King converted.
“Outstanding,” was Clark’s verdict of Hall’s impressive debut. “Rob excited us a hell of a lot and I’m looking forward to working with him.
“I thought he was brilliant when he came on. He’s got great pace and he’s very positive and direct. He commits defenders and I thought he crossed some great balls.
“He possesses a great left foot and he likes to pull the trigger. He had a shot which went wide so it’s clear he’s an exciting talent.”
