Winger prepares to face former side
The 23-year-old came through the Red Devils' Academy system, but only made one substitute appearance for the club before joining Hull following a pair of successful loan spells.
His sole visit to United since ended in a 3-0 defeat last November, and Brady told the media at Colney on Friday: "It will be great to go back, although I'm on the other side of the fence this time and looking to get a result for Norwich.
"It's exciting because I've only played there once since leaving. I still have friends there who I keep in contact with now and again; moving on was right for me and I've got no regrets.
"Manchester United was a great place to learn my trade but I'm a Norwich player now. It only takes a couple of results to change things and hopefully we can do that over the festive period, starting at United."
Louis van Gaal's men go into the contest in indifferent form, having failed to win any of their past five matches across all competitions.
Brady insists United continue to pose a significant challenge however, as he outlined: "They're still a massive club with world-class players, so we'll take nothing for granted.
