Successive thrashings away to Wellington Phoenix and at home to Sydney FC have left the one-time A-League title contenders reeling, with a berth in the finals under threat if their form does not improve.
On Friday they make the long trip to Western Australia to take on Perth Glory, who have lost only once at home this season.
And after last week promising an exhaustive analysis of what has gone wrong within the camp, Muscat revealed he included himself in that examination of the team's deficiencies.
"I certainly believe in what we're trying to do here. (But) without doubt I assess myself after last week," he said.
"I'd like to think that everyone would who is associated with the football club.
"I've got firm belief in what we do and it's been proven that when we do it right that we're a good football team and can put any team to the sword. But finding that consistency has been puzzling."
"I think the application within the structure's got to change," he said.
When pressed on whether or not he has considered packing the midfielder and playing for a draw at nib Stadium in an attempt to stop the rot, Muscat was unequivocal: "I haven't given that any thought to be honest.
"A lot's been said and will continue to be said because it puts them (pundits) in the papers and on the TV, but from my perspective, I think we're still the second and third highest scorers in the league.
"What I'm trying to say is if we apply ourselves in the right way, I think there's been enough evidence to say we're good enough."
"Ado's not available, Adama comes back in from suspension," Muscat said.
"I can't remember the last time we had a settled line-up but that's a fact, not an excuse."
"We've pushed him as much as we can in the last couple of days," Muscat said.
"I thought he was bright when he come on, obviously in difficult circumstances."
