The last time the two sides met was on the opening day of the season at Craven Cottage when Fulham inflicted a humiliating 5-0 defeat on Norwich in what was manager Chris Hughton's first Barclays Premier League game in charge of the club.
Since then Fulham and Norwich have enjoyed a mixed season and the latest encounter has acquired an extra edge as they are locked together on 28 points in 13th and 14th places in the league respectively.
Bunn was not at the club to witness the Craven Cottage demolition, joining Norwich later as understudy to John Ruddy, but he watched the game and knows the hurt it caused among his team-mates.
"It's not nice to get beaten by five so I think the boys will want to put it right with a good result," said Bunn. "Hopefully we can get a win. I think the lads will be trying to erase that memory.
"It's always massive when you play teams around you. It's vital you get the three points. It is a must-win game for Norwich.
"The last thing we want to do is get sucked into the relegation battle. It is a big game and with two home games coming up hopefully we can get two wins. When you get two wins you can go half way up the league."
