Holt says Norwich players now responding to Hughton methods
The hitman admits it took the players a few weeks to adapt to new manager Hughton's style of play.
But the result and performance against the Gunners sparked a run of five games without defeat.
Holt said: "We know if we are on our game, if we work as a unit like we did against Arsenal, we are as capable as anyone of creating chances.
"We will go out and play United very similar probably to the way we played the Arsenal game - and hopefully get the same result."
