Muñoz made four changes to his XI for the trip to Norfolk, with experienced heads Ben Foster, Kiko Femenía, Craig Cathcart and Tom Cleverley all key to a crucial win against a side that were promoted from the Championship alongside Watford last season.
But rather than be drawn on the impact of individuals, the Spaniard said the whole squad have an important part to play in delivering further wins in the coming weeks, starting with Stoke and Newcastle clashes on Tuesday in the cup, and next Saturday in the league, respectively.
He added: “Today we did make some changes. Experience was important to help in those mature situations, and I think the guys who came in did very well.
“Overall it was a good performance, but we need humility and we need to keep putting the work in.
“Hopefully if we keep doing that we can deliver some similar results at home against Stoke and Newcastle next week.”
