The coach of the navy blue and whites expects every players to contribute as the team seek to eliminate the slip-ups which saw them go down away from home last time out
None of the Victory defence covered themselves in glory during a 3-2 defeat away to 10-man Sydney FC last weekend.
But it was marquee centre-back Pablo Contreras - brought to the club specifically to minimise mistakes at the back - who bore the largest share of responsibility for the loss at Allianz Stadium.
A sterner test awaits the Victory this Saturday, with another trip to the Harbour City to face the high-flying Wanderers.
And Muscat has called on every one of his players to do their utmost to avoid a repeat of last week's calamitous defending.
"If you look back and analyse them, it was individual errors," he said.
"Collectively, when someone does make an error, because it's going to happen in games, you need make sure it's not compounded by another one. You need your team-mates to pull you out of trouble when you make an error.
"Do I blame an individual? I think collectively we could do a lot of things better."
Having missed two matches due to a ban picked up against Melbourne Heart in Round 1, Muscat is confident Contreras will soon justify the club's decision to bring in the experienced Chilean.
"It was only his second game last week," he said.
"No doubt Pablo will get better for us, because he's a very good footballer."
The Wanderers have been one of the form teams in the competitions early in 2013-14, unbeaten in five games and having won their last three outings in succession.
Despite being renowned for their tight defensive structure and ability to hit teams on the counter attack, Muscat claimed Victory have not made any special preparations for facing Tony Popovic's team.
"We've analysed the opposition and to be honest this morning in terms of the way we trained there was no real difference," he said.
"They've go their own structure and set-up and at times we are going to have to be patient. But it's not different to any other week."
As if taking on last season's premiers and beaten grand finalists was not enough, the Victory must also cope with playing at what is certain to be a raucous, sold-out Parramatta Stadium, a challenge Muscat has welcomed with open arms.
"I wouldn't know about hostile but if you're a footballer you want to go to stadiums that are full," he said.
"The atmosphere will be second to none over there. We've sold out our allocation of tickets and we've got to go there and give our fans something to cheer for."
