With a full house expected at Villa Park, including a sold-out backing of Blues supporters, it is likely to be noisy afternoon in B6.
"You have got to have people that can handle it (a derby fixture), you have got to go out and play with cool heads," said Redknapp, who will be in the dugout for the first time since taking over as Blues manager on Tuesday.
"What you don't want is people going out, going crazy, steaming into mad, crazy tackles, picking up a yellow or red card early in the game and suddenly you are out of the game.
"The first 20 minutes, I have watched lots of Villa on the videos and they are very quick out of the blocks.
"We have got to make sure we are ready for that and we keep ourselves in the game."
"They (Villa) have done okay, but were done by Reading, then they went to Fulham and got beat," continued Redknapp.
"So, we are not going to Tottenham or somewhere (like that), at the moment.
"It's a game we have got to go and try and cause them problems and be a threat.
"We don't want to sit back for 90 minutes and just kick the ball anywhere. I wouldn't know what that was, that sort of game.“
