Wales' key players

11:48am Wednesday 5th September 2007 in Sport

Alun-Wyn Jones: Whether used as a lock or on the blind-side flank, Alun-Wyn Jones is a guaranteed starter and key member of the Welsh pack.

His work in defence is energetic and he is a dynamic handler of the ball.

Jones will need to be dominant in the lineout if Wales are to secure possession from set-pieces.

Martyn Williams: Wales are at their most dangerous on turnover ball and in Martyn Williams they have one of the world's finest exponents at stealing possession. Williams was named man of the tournament when Wales were crowned Six Nations champions because his contribution on the floor was vital.

The fact he is also a good link man is an added bonus.

Williams will need to be on form in their pool match against Australia.
