"Last Saturday was a big win for us against an excellent side," Hughton told Sky Sports News. "To go into a game at Old Trafford after defeat makes it a bit harder. There's been a good feel in the camp this week.
"United have only lost one game at home this season, so the magnitude of the task is still there, but we are certainly better going into it for the result of last weekend."
Norwich were the last team to beat Manchester United in the league when they recorded a 1-0 victory at Carrow Road in November.
