After a 2-2 draw with Sunderland at the start of the month they've lost their last two.
Laudrup said: "We want to get that winning feeling back because you go from everything is perfect by winning two games and also a draw where we played very well and then suddenly you lose two games.
"You have to be careful this does not extend.
"We don't want to lose three games and then suddenly it's four games since we won the last time.
"Football turns quickly and that's why we need to get back on the winning track as soon as possible.
"This is what Tuesday can bring by going through to the next round."
