THE PURPLE haze was in a frenzy after belting West Coast by 65 points at Patersons Stadium.

Going bananas they were; waving anchors, scarves, beanies, packets of mung beans, whatever was handy.

Later in the evening, the pubs down the port were both heaving and ho-ing as dockers, painters, artists and anyone who loves Freo belted out their old bard.

But for poker-faced Freo coach Ross Lyon the magnificent, stupendous victory over the cross-town enemy was no big deal, just a "home-and-away win".

Not heave-ho? Just ho-hum?

"At the end of the day it's nothing really special," Lyon said.

"It's important for our fans and members but for me …"

Lyon didn't take a potshot at the critics who lampooned his game style after Freo's round-nine derby debacle, nor talk about its finals chances or how good eight-goal hero Matthew Pavlich was.

"After the last derby we copped a lot of criticism which was warranted, there's been some improvement along the way but we've got plenty to do," he said.

Lyon said he hadn't let the critics get to him.

"I don't take any criticism personally, it's AFL footy, you take your good ones, you take your bad ones and you move on," he said.

"It's tomorrow's fish and chip paper to be frank.

"That's not being dismissive, everyone is entitled to their opinion, that's what makes it great.

"We love television, we love media because it drives the game and gets us to the people and the fans and we are all part of a very special industry.

"So I understand the ups and the downs and it doesn't worry me too much."
