Martin Jol's side hammered the Canaries 5-0 at Craven Cottage in their season-opener.
Bunn, 28, said: "It's never nice getting beat by five goals. To have it happen in the first game of the season makes it even worse.
"The lads are still trying to erase the memory of that game. So all the boys want to get a result.
"It's definitely an added incentive to beat Fulham and we'll be looking to do just that."
