Emotions are expected to be high when Laudrup's side travel to the Cardiff City Stadium for the Premier League's first-ever South Wales derby.
"We're talking feelings and emotions here and that's why a derby is something different," Laudrup said in a press conference. "Sometimes as a manager you need to say, 'I know you feel this game very much but still you have to look at it as a football game'.
"[It is] maybe a little different but it is still a game against 11 where you have to think with your head and play with your feet. You cannot let your emotions drag yourself towards something because we want to win the game and not play with one less."
The Swans sit ninth in the Premier League table, while their opponents are two points behind in 16th.
