Postecoglou has stated the performance in the derby will be more important than the result.
He said, "We're five games in. I understand that for many people, they will see this as our first real test and I get that.
"It is pretty easy, you could almost write two stories now. If we are successful, great, we're on the right track. If we're not, we've still got a long way to go. For me, what is going to be more important is how much of our football I see in a big game like this. How much of us can I see against a top opponent?
"That will give me the biggest indicator of where we're at but, ultimately, we'll still be six games into a new cycle, a new group of players, a very young group of players. Either way, irrespective of the outcome, I'd say the performance will be my biggest measure, but knowing we still have a long way to go."
