Turner, for one, is determined to spoil the party for Williams, despite admitting he owes a lot to the Welsh wizard.
''Shane has really changed the way wingers play the game,'' Turner said. ''Previous to him, the winger was the guy who sat at the end of the back line, and finished off tries, whereas he really changed that by coming in and being a ball-playing threat right across the park.
"I learnt a valuable lesson from him several years ago, when in the first 20 minutes of a Wales-Australia Test, Shane scored a try, and set up two others - not one of them was on his wing.
'That really changed the game, and Wales went on to beat us quite convincingly. That showed to me how a winger can really assert themselves on a game by finding some of the bigger players [in the opposition]. And that's something I'm constantly doing now - scanning the field, looking for mismatches involving some of the bigger, slower boys around the field, where you can do some footwork on.
''This is a big chance for me to show Robbie and the selectors that I am good enough to be at this level,'' Turner said.
