Former Australian fullback Greg Martin said on Tuesday Genia would be dumped from the starting side, elevating White and installing Ben Mowen as captain.

Wallabies coach Ewen McKenzie will name his team on Wednesday ahead of the must-win Test against Argentina in Perth on Saturday night. It's understood White has been training as the No.9 this week.

White's Brumbies teammate Matt Toomua is also in line for a recall to the No.10 jersey at the expense of Quade Cooper.

But former Wallabies coach John Connolly says dumping Genia would rob Australia of its only world-class player and be a bizarre move to try to snap a four-game losing streak.

''He [McKenzie] talked about dumbing things down – maybe they're playing too complex a game plan,'' Martin said.

''They've got a Test in Perth against Argentina on Saturday night – they will be dropping Will Genia to the bench and replacing him with Nic White. Ben Mowen, playing No.8, will become the new captain of the Wallabies.''

Moving Genia – regarded as one of the world's best No.9s – to the bench would leave a gaping hole in the squad's experience with Mowen having played just six Tests and White having made his international debut last month. But after an embarrassing loss to South Africa last week, it would signal McKenzie's intentions to make hard decisions to get success.

Regular captain James Horwill is still recovering from a hamstring strain.

''It would be a strange move [to drop Genia] because I think he's arguably one of Australia's only world-class players,'' Connolly said.

''Genia has played so much footy, he takes the role of a back-rower and really gets involved so that can take its toll. Nic White's form has been solid as well. But it all comes down to how you react to a loss ... there's a lot more to it. The go-forward of the back row is a massive issue.''
