There is plenty at stake this Saturday when New Zealand and Australia go head-to-head in the Rugby World Cup final.

And it's not just winning the Webb Ellis trophy for a third time.

It's an opportunity to deliver defeat to a regional rival and that is already starting to warm up in the press. 

The Sydney Daily Telegraph have got their digs in early on All-Blacks skipper Richie McCaw, who is free to play in the final, converting him into creepy-crawly dubbed the 'Richetty Grub'.

Writing in The Daily Telegraph James Pandaram claims: "The Richetty grub, aka Richie McCaw, hails from Oamaru in New Zealand and is known for its dubious breakdown tactics, electrical tape around its large head and smug grin on its face.

"Whether it's coming in illegally from the side, rolling away from the maul the wrong way to disrupt the halfback's passing, or holding on to the tackled player too long, the Richetty grub is the master of the dark arts of breakdown cheating."
