THERE is a "disruption" Sydney can cause to Brisbane's game to have a chance of overcoming the two-time reigning premier on Saturday afternoon, according to Michael Voss.
The Lions were 43-point winners over the Swans when the teams met in round 16, and Sydney will be undermanned in Saturday's qualifying final due to the suspensions of Isaac Heeney, Chad Warner, Nick Blakey, James Jordon and Riley Bice.

The Swans' handball game has been a trademark this year and in that clash at the Gabba, they had 722 handball metres gained.
In games where Sydney has had more than 600 handball metres gained this year, it has a win-loss record of 12-2, with that round 16 game one of the two defeats.
Voss noted the Swans had made some changes as the previous meeting went on, and he believes they will need to manage it again to have any chance of securing a home preliminary final.
"There was a subtle adjustment that Sydney made throughout the game," the three-time premiership winner said on AFL.com.au's Finals Film Room.
"As the game played out, they started to hold their forwards just a little bit longer and create some transition space.
"They just create that transition room between the contest and the actual forwards, so it makes the Brisbane defenders decide: 'Do I come forward, or do I go back?'
"They have to create that decision and create that disruption if they're going to hit the scoreboard against Brisbane in this game."
Voss believes it is too late in the campaign for Sydney to make major changes to its game style as it looks to adapt following the suspensions handed to their five players.
The former Carlton coach said the Swans should "go down swinging".
"I think you've still got to stick with it. They might change it a little bit, but ultimately being able to play this style, it's a little bit too late to change," Voss said.
"You might be able to make some subtle changes, but this is their style. So go down swinging. If you're going to go down, go down your way.
"What Brisbane was able to do last time was take the corridor off them and make sure they came forward on any forward handball that they were able to generate."
