The 14-cap flyer is renowned as one of the fastest rugby players around, but has looked to alter his style to add an extra yard of pace.

And he hopes it will help him in ending a try drought that has only seen him score one try since the World Cup.

I have seen myself on tape and my hips do go everywhere, and I know it's a different style from everyone else. It's pretty unique, he admitted.

It's a style that probably was responsible for all my hamstring problems that kept me out for so long. It was suggested that there was probably too much rotation in my hips.

So it's always a good thing to learn something that makes you fitter, faster and stronger.
In the end, the hope is that the change in running style will put a yard of pace on me, but it's not the sort of thing that's going to happen overnight.

Doug Howlett has been an out and out sprinter in his time and he has got the perfect running style. If you watch him running he nearly hits himself in the face with his knees.

He is one of the quickest in the world so there must be something in it.

Having been brought back into the international fold for the World Cup after more than a
year in the wilderness, Williams believes he is close to top form.

I feel I'm a better rugby player now than I've ever been. I'm more experienced, more confident and I'm hungrier for the ball. Instead of staying on my wing I go looking for work a bit more, he said.

I just feel I'm a better all-round player and I don't think I have enjoyed my rugby so much.

I'm definitely due a try, but you can't say where it's going to come from these days because defences are so good."
