The Victory became the first team in 11 matches to lose to the Glory, who were led by former Liverpool star Robbie Fowler’s hat-trick, enabling the Western Australians to salute 3-1 at nib Stadium.
Merrick was keen to strike that one from the records and move on to Thursday’s home clash with Central Coast Mariners.
"A game like that you just have to forget about and move on," Merrick said.
"If it was front third stuff or a defensive error you'd work on it, but just too many things didn't go right.
"I would say that's probably only the second game this year where our defence hasn't played well.”
Despite a recent form slump which has seen the Victory drop their past two, Merrick was confident his side would be there come finals time.
"I think we've got the team to enter the finals and we'll worry about the finals when we get there,” he added.
"I'm kind of glad we've got a short turnaround. I think that will be good for us."
