Wallaby vice-captain Will Genia believes that his side are more than capable of stopping the powerful running of Jamie Roberts.
Roberts returns to the Lions midfield after a spell on the sidelines due to injury and his partnership with Jonathan Davies - and the resulting omission of Brian O'Driscoll - has been one of the biggest talking points heading into the deciding Test in Sydney.
Genia is well aware of the danger that Roberts poses, but is confident that he will be keep quiet on Saturday.
"Jamie's a big guy and he was probably in their plans to play right throughout the series if it wasn't for injury.
"He brings that direct running game and he's big and hard to stop, I've played him a couple of times.
"The focus on him is to make sure we tackle low and don't allow him to get too much over the advantage line and get them front foot ball.
"That's been a big focus for us all week. On the back of injury to his hamstring it's good to see him get an opportunity in the last Test."
Regardless of the final outcome of the series, Genia insists that just being involved in such a prestigious contest has been an honour.
"I'll never forget this. Living and breathing it now, I feel so lucky, blessed and privileged to be here and be a part of this series," he said.
"It happens once every 12 years. It's incredible to be a part of the intensity and passion a Lions tour brings to Australia.
"It's something I'll look back on and will have fond memories of, regardless of what happens on the weekend. I've loved every second of it."
