Victory have won three of their past four matches including last week’s extra-time 1-0 win over Melbourne City.
Muscat says a focus on attitude is paying dividends as his side attempt to climb from fifth on the ladder at AAMI Park.    
“Every action is secondary to attitude, and normally your actions are a reflection of your attitude,” Muscat said.
“We’ve been a lot more proactive and a lot more aggressive in our attitude in the last two weeks.”
Muscat said an honest appraisal of his side’s shortcomings was the catalyst for their recent form spike.   
“The easiest things to do when things aren’t perceived to be going well is change for the sake of change and hope,” he said.
“We removed hope by analysing and being fairly critical of ourselves as a group, and once you identify where things can be better you’re halfway to improving things.”
Muscat said the Newcastle fixture came at a good time as his side looks to build on recent momentum.
“We look forward to tomorrow night’s game, Newcastle are sitting second on the table and they’ll certainly pose some different questions and problems for us.
“It’s a really good challenge and it’s come at a good time for us so we look forward to it.”
