Brighton were in the bottom half of the Coca-Cola Championship but put on a fine show in that January clash at the Lane.
Indeed, it took a Robbie Keane special to win the tie five minutes from time and deny the Seagulls a replay after Richard Carpetner had equalised Ledley King's opener.
Forest are struggling second from bottom of the Championship but as Chris states, that will mean little come Sunday.
"It's a home tie against a non-Premier League side but we have to go about the task in an appropriate manner," said coach Chris.
"You only have to look at the Brighton game. They came to the Lane, played very well and possibly deserved a draw on the day.
"It looked like it was heading that way until Robbie's spectacular late goal. That's a reminder because we didn't play particularly well and it could have been a different outcome.
"The players are aware of how important this competition is to the club and the fans and will take that into Sunday."
Chris Hughton will use the example of Brighton in round three as a reminder that we have to get things right against Nottingham Forest in the fifth round of the FA Cup on Sunday.
