Blues struggled to get a foothold in the game and former St. Andrew’s favourite DJ Campbell pounced after just seven minutes to score the only goal.
Clark’s side had a number of opportunities to claim at least a share of the spoils in the second half, but failed to convert their chances.
The defeat was Blues’ third in their last four home games and Clark was particularly unhappy that his side failed to follow instructions and build on their last two away games against Millwall and Leeds.
“I was disappointed with the first half because we’d come off the back of a good week,” said Clark.
“You know they’re (Ipswich) going to be buoyed by the new appointment of the manager. But we’ve got to come out of the traps and play at a high tempo and we didn’t do it or all the things I’d asked of them.
“We didn’t play in Ipswich’s half of the pitch in the first 15 or 20 minutes and get the ball up to the strikers, play off them or take gambles in terms of wide men. We played into their hands and the goal was absolutely dreadful. It’s not the first time it’s happened. We’ve told young Nathan time and time again about squaring back passes across the pitch.
“I expected them to go forward and be positive, but the whole first half we just thought we could turn up and play and continue where we left off and try and be a pretty footballing team, but we’ve got to earn the right. You’ve got to play a high tempo and win the battles and win second balls, and you’ve got to compete and have every single player doing that.”
Blues improved somewhat after the break and they enjoyed their best spell of the game following the introduction of Nikola Zigic.
“We should have won the game really,” continued Clark. “In reality we should have won it 3-1. We had three great chances – two from Nikola, who I thought was excellent when he came on. He usually sticks those chances away, but we also had other opportunities for Curtis etc.
“When it gets to desperate situations 15 minutes from the end we do the things we’re expecting from the first minute. We put crosses in the box, there are people running off people who are trying to head it to try and get the second ball. We’re doing all those type of things which we haven’t been doing in the first. Do we think teams just let you play and go and win the game? Of course they don’t.
“We’re giving ourselves too many problems and issues. We’re creating a negative attitude around the stadium with our first half performance.
“If we play like we did in the second half with a bit of spirit and creating chances and put the opposition under a bit of pressure the crowd are with you and right behind you. But if you are flat and there’s no movement off the ball, and it's slow and pedantic and you don’t create anything, of course it’s going to create a quiet atmosphere. I’m not blaming them. We’ve got to do it and we have done it. It’s the inconsistency that’s frustrating us.”
