PORT Adelaide will look to attack Hawthorn physically on Friday night as it continues its hunt for respect in the final month of the season.

Challenged by coach Ken Hinkley last week to find the physicality missing from its 64-point humiliation against the Western Bulldogs in round 19, Port was the aggressor against Greater Western Sydney.

Hinkley told his playing group to "play tough" against the Giants and defender Jackson Trengove said the instruction would remain this week.

He believed aggression had played a huge part in the Hawks' long-term success and would help his side enter the pre-season with genuine momentum.

Trengove tipped Port to not only go hard at the man at Etihad Stadium, but also to play a fast and ferocious brand of football as it did in the first half against the Hawks in round four.

The Power built a 58-point lead in the second term on the back of lightning quick attack.

"That's (aggression) why they've been so good I think for so long, they do that every single week," Trengove said.

"We fired ourselves up for the weekend and the challenge this weekend is to back that up and go again.

"Win or loss, as long as we play that Port Adelaide football – that hard footy and really respect each other – I think that's going to go a long way to us building form into next season."

Trengove admitted the Power had stopped playing for each other at times in a season that had disappointed so much, something he said was natural given the dip in form and confidence.

"We're a really close group, but I think when your form's down, individually and the team's form is down, you sort of lack that little bit of passion and team-first [mentality]," he said.

"You start to think about yourself – it's human nature when you're not going as well as you know you can be.

"For us it was just about opening up, not worrying about yourself, thinking about the team, and I thought on the weekend, just the way we played team footy and cared for each other, it was half the reason why we got the win."

Trengove spoke on Tuesday morning to raise awareness for brain injury week, for which he has been an ambassador for three years.

There are 700,000 Australians with a brain injury and Trengove said improving awareness in the community strengthened the chance of helping those in need.
