"I'm very pleased with the performance of the side tonight. I've been hoping we would do that to someone sooner rather than later, and it's a tremendous confidence booster for the boys," said the Mariners boss.
 
"We played the way I wanted them to play."
 
Arnold praised the contribution of his younger players.
 
"I thought our young guys were outstanding tonight. Young Mathew Ryan pulled off a great save that could have got Perth back into the game, and Mustafa(Amini)  is full of confidence.
 
"You never know what the young boys can do until you give them the chance. So why not?"
 
When asked if it was one of the greatest wins in the club's history, Alex Wilkinson was diplomatic.
 
"I don't actually have the greatest memory, but it was definitely a great performance particularly after our last game against Brisbane," he said.
