Besieged Brisbane Lions coach Michael Voss admits his side must start reversing their fortunes against AFL newcomers Greater Western Sydney on Sunday.

Three big losses have placed Voss under the spotlight – and losing to the AFL rookies at the Gabba this weekend will only intensify the glare.

Lions chairman Angus Johnson this week backed Voss after their latest defeat – a 58-point thumping from Collingwood – but claimed a few players had to “have a long, hard look at themselves”.

Asked if some players had to lift, Voss said in Brisbane on Wednesday: “I think we all do.

“If you lose three in a row you have to do things better.

“We are still short of where we need to be.

“Clearly we are all working towards that.

“I know all the players are passionate about it.

“We are all in it to try and turn that around and it has to start this week.”

The Lions’ glory days must seem an eternity ago for three-time premiership captain Voss.

Brisbane have not finished higher than 10th in six of their last seven seasons.

The Lions are 2-5 after seven rounds, tasting victory only against the win-less Gold Coast Suns and Melbourne.

However, Voss said lessons learned from 2011’s shock loss to debutants Gold Coast would ensure the Lions would not take GWS lightly on Sunday.

“We’ve already been exposed to this sort of thing,” he said.

“If we want to have a reminder of what happens when you potentially take a team for granted, then we’ve got a short memory.

“We won’t be resting on our laurels that’s for sure.

“They (Giants) have got good bodies and they are prepared to run so if we are not on our guard we will be left for dead.”
