"We've just got to be more consistent. But sometimes you've just got to say 'Look, this is exactly how it happened'.
"We're looking forward to the next game and how we're going to make it better, because if you're going to learn a lesson from that game and benefit from that type of game against Wanderers you've got to be blatantly honest and say 'These are the things we need to work on'."
Playmaker Michael McGlinchey put Merrick's displeasure down to the Wellington-based outfit's sense of purpose and high expectation this campaign.
"The standards we set ourselves, he's not happy," said McGlinchey, who is back to full training after last week's lighter load on return from international duty.
"It wasn't too bad, but I think we've set ourselves pretty high standards this season.
"We want to stay in that top little cluster (on the table) and we want to get up into the top-three positions.
"A win this week would definitely put us up there. We can play good enough to do that."
Having played under Sydney FC coach Graham Arnold during his time at Central Coast, McGlinchey was expecting danger.
"Graham Arnold's teams are always the same - very compact, very strong in defence, but they've also got that quality in the final third," he said.
"They can turn it on at any time, so we'll be very cautious of them."
Defender Ben Sigmund is back in Wellington and has been ruled out of the match with likely concussion.
Midfielder Vince Lia is expected to play in his place in his first match back in nearly a month since tearing his hamstring.
