"It was [a great performance] and in difficult conditions really, not just with the weather but with the pitch here," he told 'Sky Sports'.
"The determination and attitude of the players was everything one could hope for and luckily, we got the goals this time. It is an important victory because we are playing teams around us at the bottom of the table and every time you get points, you improve your score and of course, take away from theirs.
"I thought James Tomkins and young Aaron Wan-Bissaka were very good today. We've got to keep these performances up and we're going to need seven more of them if we want to stay in the league.
"But it was very encouraging today at least to come to a place like Huddersfield where everyone knows how hard it is to win and go away with the three points. I hope that is going to give us some type of boost and confidence for the future."
Palace are now two points clear of relegation in the tightest relegation scrap ever.
