Blues skipper Luke Chambers says he and the rest of the squad are still hurting after Saturday’s 2-0 home defeat to his former club Nottingham Forest.
"It's good to have another home game this weekend as we are itching to put right the Forest result," Chambers told the club site.
"We are still hurting from that result. Everyone was flat after the game and it's about picking yourself up and going again now.”
The 31-year-old says Saturday’s visitors QPR will be buoyed after new boss Ian Holloway’s first game in charge ended in a 2-1 home victory over Norwich City.
"We've got a tough game against QPR to focus on now, who will come here galvanised after winning at the weekend under their new manager,” he added.
"Ollie has immediately had an impact there but we don't want that to continue on Saturday at our place.
"We are in all this week to train and I'm sure the gaffer will have us working on a few things.
"We've conceded a few rubbish goals recently, from a defensive point of view, and that has to be addressed."
