Bunn was not at the club when the Canaries were thrashed 5-0 on the opening day of the season at Craven Cottage.
However, he is aware how much that result hurt his team-mates and he knows they are keen to make amends in front of their own fans this weekend.
"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."
