Pardew believes that his players will be buoyed by their efforts against United despite going out of the competition.
He told Sky Sports News: "I thought we played terrific out there, the young lads can gain confidence from that. At times we were every bit as good as United tonight and we deserved more.
"I said before hand that a goal for Cisse would change his mood, and after that he looks really good for Saturday."
