He's arguably already proved his worth since arriving in New Zealand but Sonny Bill Williams is refusing to rest on any laurels as he targets retaining his place in the All Blacks.

The bulky midfielder's trained with the Crusaders in London overnight as they build up to Monday morning's historic Super Rugby match against the Sharks at Twickenham.

Williams has become one of the game's big drawcards but he's desperate to prove his desire for more.

He says he wants to achieve things people say he can't achieve.

The Crusaders trained overnight at the British Army's Honourable Artillery Company near Moorgate in the centre of town.

It's prime London real estate with a shovel of dirt on the six acre site said to be worth around $NZ60,000.
