Sonny Bill Williams has rejected a massive offer from his French rugby club to chase a spot in the All Blacks side for next year's World Cup. Williams, who has been playing for Toulon since walking out on NRL club the Bulldogs in 2008, will announce an 18-month deal with the NZRU this week, Fairfax has reported. The 24-year-old has not yet decided which NZ-based Super rugby side he will link with, the report said. But Williams and his partner both have family in Auckland, the home city of the Blues. Toulon reportedly tabled a three-year offer to Williams worth $6 million, while the NZRU could only come up with $550,000 per year. Williams could be playing provincial rugby in NZ within weeks and is eyeing a place in the All Blacks' spring tour squad, which will play a Bledisloe Cup Test against Australia in Hong Kong on October 30.
