James Hook is being backed by former Welsh stars to don the 12 jersey when Wales take on South Africa in the first of the 2015 Rugby World Cup quarter-finals.
The Wales camp has been hit by injury, the latest being Liam Williams who will miss the last eight clash due to a foot injury.
Former Wales flanker Martyn Williams believes coach Warren Gatland needs to throw a curve ball against the Springboks if they have any hope of winning.
Williams indicated that playing Hook at inside centre could create some indecision amongst the South African backs.
"If you're going to beat South Africa, probably, you will need that little bit of X-factor, that little bit of magic," quipped Williams.
"You won't out-muscle them so needs must."
Meanwhile, former Welsh pivot Jonathan Davies echoes Williams' sentiments, saying that the time is right to try something different, especially with centre Jamie Roberts providing some versatility.
"I think we need to think differently now and Jamie and Hooky can play left and right," said Davies.
"This is an all-or-nothing game and he might offer something different. James can kick, Jamie can take it up the middle.
"James Hook's distribution is a little bit better so I would play him at 12 and swap them back and fore."
Wales will take on South Africa in the weekend's first qurter-final on Saturday at Twickenham.
