THE BRISBANE Lions can’t afford to roll over this week against Fremantle, according to assistant coach Shane Woewodin.

The 2000 Brownlow medallist said the Lions can’t dish up a performance against the Dockers in Perth like the one they delivered at home against GWS last week.

"We want to be really competitive, that's foremost," Woewodin said.

"We don't want to roll over like we did last week.

"That was a really poor effort from our group, particularly in the back half of the game. (We need to) be competitive, last longer in the game and be there at the end.

"It doesn't matter where you play, you have just got to be on song on the day.

"If you're not, you get your pants pulled down, no matter where you play."

The Lions face a daunting task this week. They have not won at Patersons Stadium in their last four attempts and they have not beaten the Dockers since round 16, 2009.

In the last two matches against Fremantle in Perth, the Lions have kicked just five and six goals respectively.

"We have struggled to score in the past," Woewodin said.

"We have just got to be a lot smarter with the footy and how we use it, be a bit more composed with the footy and hopefully a bit smarter with our efficiency and our effectiveness going inside 50.

"Our smalls hopefully can come into the game a bit more and they've been in good form so hopefully they can put some pressure on the Fremantle defence."

Fremantle coach Ross Lyon has mentioned the Lions' "three amigos" Dayne Zorko, Josh Green, and Lewis Taylor as potential dangers on Saturday and Woewodin said their importance was heightened given the absence of Jonathan Brown with concussion.

"Daniel Merrett comes back into the group so there's another big body," Woewodin said.

"We are going to play Michael Close again as another key positional player.

"Hopefully our ground level boys can get to work.

"They’ve been in good form and put a lot of pressure on and hit the scoreboard as well. They're hard to play on. There's a bit of speed there."

Despite a lot of external discussion this week about Brown's future, Woewodin is adamant it hasn't affected the playing group.

"It hasn't been a talking point at all," Woewodin said.

"Browny's had a couple of days away from the club to get himself right and have some time to rest and spend some time with the family down on the farm.

"We haven't spoken about it. He has been around the club mentoring as he normally does every week with Closey and a few others so it's business as usual."
