Manager Alex McLeish insists there will be no hangover from the five-goal mauling at Old Trafford in Birmingham's biggest game of the season next week.
McLeish's side tackle West Ham at St Andrew's on Wednesday hoping to secure a Carling Cup final date with either Arsenal or Ipswich on February 27. Unfortunately, the warm-up did not quite go as planned.
In adopting a bold approach against Manchester United, McLeish was hoping to catch Sir Alex Ferguson's men off guard.
Instead, it was United who made the flying start, eventually condemning Birmingham to their biggest defeat of the season.
McLeish now faces the tricky task of trying to raise morale, although he does not feel it will be too much of a problem.
"We have a bunch of players who will bounce back well," McLeish said. "There is evidence they have that in their locker. People will say taking this drubbing will affect their confidence, but that is not the feeling I got from senior players in the dressing room. They were more angry than anything else."
