Wales forward Aaron Shingler has described the possibility of an autumn Test series whitewash as "almost unthinkable".
That scenario will unfold, though, for last season's World Cup semi-finalists and RBS 6 Nations champions if they lose to Australia at the Millennium Stadium on Saturday. They have lost seven Tests in a row to the Wallabies, but four of those reversals were by six points or less.
"Next weekend means everything," said Shingler, who replaced an injured Bradley Davies just three minutes into Wales's 33-10 defeat by world champions New Zealand on Saturday. "Everything is on the line. It's important we don't come away with four losses. It is a massive, massive week ahead."
He added: "We've got to be very accurate, very aggressive and look to bully them (Australia).
"A whitewash is almost unthinkable. We've trained well every week, our preparation has been good, it just hasn't gone as we would have liked on the field."
